Gender neutrality in Spanish
Feminist language reform has proposed gender neutrality in languages with grammatical gender, such as Spanish. Grammatical gender in Spanish refers to how Spanish nouns are categorized as either masculine (often ending in -o) or feminine (often ending in -a). As in other Romance languages—such as Portuguese, to which Spanish is very similar—a group of both men and women, or someone of unknown gender, is usually referred to by the masculine form of a noun and/or pronoun. Advocates of gender-neutral language modification consider this to be sexist, and exclusive of gender non-conforming people. They also stress the underlying sexism of words whose feminine form has a different, often less prestigious meaning. Some argue that a gender neutral Spanish can reduce gender stereotyping, deconstructing sexist gender roles and discrimination in the workplace.

Grammatical background 

In Spanish, the masculine is often marked with the suffix -o, and it is generally easy to make a feminine noun from a masculine one by changing the ending from o to a: cirujano, cirujana (surgeon; m./f.);  médico,  médica (physician, m./f.) If the masculine version ends with a consonant, the feminine is typically formed by adding an -a to it as well: el doctor, la doctora. However, not all nouns ending in -o are masculine, and not all nouns ending in -a are feminine:

 Singular nouns ending in -o or -a are epicene (invariable) in some cases: testigo (witness, any gender).
 Nouns with the epicene ending -ista, such as dentista, ciclista, turista, especialista (dentist, cyclist, tourist, specialist; either male or female) are almost always invariable. One exception is modisto (male fashion designer), which was created as a counterpart to modista (fashion designer, or clothes maker).
 Some nouns ending in -a refer only to men: cura ("priest") ends in -a but is grammatically masculine, for a profession held in Roman Catholic tradition only by men.

Invariable words in Spanish are often derived from the Latin participles ending in -ans and  -ens (-antem and -entem in the accusative case): estudiante. Some words that are normatively epicene can have an informal feminine ending with '-a'. Example: la jefe; jefa. The same happens with la cliente (client); "la clienta".

The syntactic case of what is commonly referred to as masculine has been shown to primarily fulfill the role of gender neutrality within the language; the name masculine is inherited from Latin, but does not reflect the broader utility of the grammatical structure relevant to social gender. "Any lexical item subcategorized for gender will be specified, for example, as being feminine or it will carry no gender specification at all."

Social aspects 
Activists against sexism in language are also concerned about words whose feminine form has a different (usually less prestigious) meaning:

 An ambiguous case is "secretary": a secretaria is an attendant for her boss or a typist, usually female, while a secretario is a high-rank position—as in secretario general del partido comunista, "secretary general of the communist party"—usually held by males. With the access of women to positions labelled as "secretary general" or similar, some have chosen to use the masculine gendered la secretario and others have to clarify that secretaria is an executive position, not a subordinate one.
 Another example is hombre público, which translates literally to "public man", but means politician in Spanish, while mujer pública or "public woman" means prostitute. 
One study, conducted in 2014, looked at Spanish students' perception of gender roles in the information and communication technology field. As predicted, the study revealed that male and female Spanish students alike view ICT as a male-dominated field. This could correlate to the use of gender in Spanish language, including the use of masculine nouns in many historically male-dominated fields (see examples above).

Reform proposals 
In Spanish, as in other Romance languages, it is traditional to use the masculine form of nouns and pronouns when referring to both men and women. Advocates of gender-neutral language modification consider this to be sexist and favor new ways of writing and speaking. One such way is to replace gender-specific word endings -o and -a by an -x (such as in Latinx, as opposed to Latino and Latina). It is more inclusive in genderqueer-friendly environments than the at-sign, given the existence of gender identities like agender and demigender and/or the existence of gender-abolitionist people. One argument is that the at-sign and related symbols are based on the idea that there is a gender binary, instead of trying to break away with this construct, among others.

A list of proposals for reducing the generic masculine follows, adapted from the Asociación de Estudios Históricos sobre la Mujers 2002 book, Manual de Lenguaje Administrativo no Sexista:

In recent decades, the most popular of gender neutral reform proposals have been splitting and the use of collective nouns, because neither deviate from Spanish grammar rules. They don't sound awkward in speech, so they are more widely accepted and used than the other examples listed above.

Work by Ártemis López distinguishes between Indirect Non-binary Language (INL) and Direct Non-binary Language (DNL) in Spanish. Indirect Non-binary Language utilizes many of the tactics listed above, such as using collective nouns, dropping the subject, or using metonymy in ways that avoid use of gender in the sentences. Direct Non-binary Language, however, uses neologisms and neomorphemes to "accurately reflect the non-binary reality of the world"

 Pronouns 

Some Spanish-speaking people advocate for the use of the pronouns elle (singular) and elles (plural). Spanish often uses -a and -o for gender agreement in adjectives corresponding with feminine and masculine nouns, respectively; in order to agree with a gender neutral or non-binary noun, it is suggested to use the suffix -e. This proposal is both to include people who identify as nonbinary and to remove the perceived default in the language as masculine.

 Replacing -a and -o 
There are several proposed word endings that combine the masculine -o and the feminine -a.

 Writing 

 Pronunciation 
An argument used against both the use of the ampersat as a letter and the use of -x for gender-neutral endings is that the resulting words are rendered unpronunceable. It is also argued that these endings, while attempting to be inclusive in regard to gender identity, would exclude people who, due to being visually impaired, illiterate, or having a disability such as ADHD or dyslexia, rely on screen readers. However, it has been proposed that using -e instead would solve the issue, as the resulting words would be easily pronounced.

The Diccionario panhispánico de dudas, published by the Real Academia Española, says that the at-sign is not a linguistic sign, and should not be used from a normative point of view.

 Political use 
Some politicians have begun to avoid perceived sexism in their speeches; the Mexican president Vicente Fox Quesada, for example, commonly repeated gendered nouns in their masculine and feminine versions (ciudadanos y ciudadanas). This way of speaking is subject to parodies where new words with the opposite ending are created for the sole purpose of contrasting with the gendered word traditionally used for the common case (like felizas and especialistos in felices y felizas or las y los especialistas y especialistos).

There remain a few cases where the appropriate gender is uncertain:

  used to be "the president's wife", but there have been several female presidents in Latin American republics, and in modern usage the word generally means a female president. Some feel that  can be treated as invariable, as it ends in -ente, but others prefer to use a different feminine form. The usage is inconsistent:  is often used for female customers, but *cantanta is never used for female singers.
 El  (the policeman). Since la policía means "the police force", the only productive feminine counterpart is la mujer policía (the police woman).''' A similar case is  (meaning both "music" and "female musician").
  ("male judge"). Many judges in Spanish-speaking countries are women. Since the ending of juez is uncommon in Spanish, some prefer being called la juez'' while others have created the neologism .
