Transitive verb in the reciprocal form expresses that its two core arguments (the Actor and the Undergoer) act on each other simultaneously. The reciprocal form has the prefix зэры~ (zara~), for example:   To indicate the way a certain action is performed, the prefix зэрэ~ (zara~) and the suffix ~рэ /~ra/ are added. The prefix зэрэ~ (zara~) and the suffix ~рэ /~ra/ can also be used to indicate a fact. To indicate an event that happened instantly at the beginning of a certain verb, the prefix зэрэ- (zara-) and the suffix -эу / -ыу (-aw/-əw) are added. Can only be used on verbs and nouns. It is posited most often before root of verb, after all other prefixes. When to use this Prefix :  умыкӀомэ /wəmkʷʼama/ "if you don't go", умыкӀорагъоми /wəmkʷʼaraːʁʷami/ "even if you don't want to  go", мамкӀуу /maːmkʷʼəw/ "while he didn't want to go". Cannot be used simultaneously with both the negative prefix (мы~) (mə~) and the negative suffix (-п) (-p). To indicate a verb that someone wishes to happen, the verbal infix ~рэ~ (~ra~) is added. Examples :  Questions are indicated by the suffix ~a /aː/, which, in verbs that end with /a/, lengthens the end vowel. If question is posited to word having negative suffix ~п (~p), it is converted to suffix ~ба (~baː). for example:   Optative mood is expressed with the complex suffix ~гъот or ~гъует or ~гъэмэ :  The verbal suffix ~жь (~ʑ) designates recurrence/repetition of action. It can also be used to indicate an action that someone was doing before and now continuing it.
