  Indeed.
  To extend it a little bit further, adjectives do not have a plural form in English.
  Certain other languages, however, do have plural adjectives which are used when the noun it corresponds to is plural.
  For example, in Spanish, "happy dog" is "perro feliz" but "happy dogs" is "perros felices" with both the noun and the adjective taking a plural form. Hebrew & Arabic hav the fun extra of a "dual" form for something there's a "pair" of, in addition to the more familiar plural :-P
  The same also applies to gender of words, by the way, so a masculine noun gets a masculine adjective while a feminine one gets a feminine one (cf "chica alta" vs "chico alto" for tall girl/boy)
context: This is a friendly reminder to read our rules.
  Remember, /r/Showerthoughts is for showerthoughts, not "thoughts had in the shower!"
  (For an explanation of what a "showerthought" is, please read this page.)

  The designers at Packard, in 1900, are the originators of the "glove compartment" in the first "dash boards" 
  Previous to this, there was a "Gloves Box" that was for the driving gloves and predates cars as Buggies had Drivers outside. 
  So when it went from actually storing Gloves as it's sole purpose. 
  It became a Glove Compartment, that can hold anything, with a kind nod to the origin. 
  The more you know :) >
  
  Well, that's an interesting twist! We should all start calling it a glove compartment, no matter how many gloves we store in there. After all, why should the number of gloves determine the name of the compartment? ;) >

  this is like how it’s called a chocolate box not a chocolates box, even though they comprise several chocolates… or a shoe box, even though there are two shoes… or a car park in british english, or a color wheel, or a student body… i think when the noun takes adjective form, it usually goes into singular form
