of declension. Case agreement is not a significant feature of English (only personal pronouns and the pronoun who have any case marking). Agreement between such pronouns can sometimes be observed: Who came first – he or his brother? vs. Whom did you see – him or his brother? Alliterative agreement A rare type of agreement that phonologically copies parts of the head rather than agreeing with a grammatical category. For example, in Bainouk: In this example, what is copied is not a prefix, but rather the initial syllable of the head "river". By language Languages can have no conventional agreement whatsoever, as in Japanese or Malay; barely any, as in English; a small amount, as in spoken French; a moderate amount, as in Greek or Latin; or a large amount, as in Swahili. English Modern English does not have a particularly large amount of agreement, although it is present. Apart from verbs, the main examples are the determiners “this” and “that”, which become “these” and “those” respectively when the following noun is plural: this woman — these women that dog — those dogs All regular verbs (and nearly all irregular ones) in English agree in the third-person singular of the present indicative by adding a suffix of either -s or -es. The latter is generally used after stems ending in the sibilants sh, ch, ss, or zz (e.g. he rushes, it lurches, she amasses, it buzzes.) Present tense of to love: In the present tense (indicative mood), the following verbs have irregular conjugations for the third-person singular: to have: has to do: does to say: says Note that there is a distinction between irregular verb conjugations in the spoken language and irregular spellings of words in the written language. Linguistics generally concerns itself with the natural, spoken language, and not with spelling conventions in the written language. The verb to go is often given as an example of a verb with an irregular present tense conjugation, on account of adding "-es" instead of just "-s" for the third person singular conjugation. However, this is merely an arbitrary spelling convention. In the spoken language, the present tense conjugation of to go is entirely regular. If we were to classify to go as irregular based on the spelling of goes, then by the same reasoning, we would have to include other regular verbs with irregular spelling conventions such as to veto/vetoes, to
