The following examples come from serbokroatic: in the case of verbs, conformity between the sexes is less frequent, although it can still occur. For example, in the past French compound, in certain circumstances, the past part corresponds to the subject or an object (see past compound for details). In Russian and most other Slavic languages, the form of the past in sex corresponds to the subject. There are also matches in the number. For example: Vitabu viwili vitatosha (Two books will be enough), Michungwa miwili itatosha (Two orange trees will be enough), Machungwa mawili yatatosha (Two oranges will be enough). In English, defective verbs usually do not show a match for the person or number, they contain modal verbs: can, can, must, must, must, must, should, should, should. .
