Almost all verbs have a third person singular present indicative form with the suffix "-s". In terms of spelling, it is formed in most cases by adding "-s" to the verb's base form: "run" → "runs". However if the base form ends in one of the sibilant sounds (, , , , , ) and its spelling does not end in a silent "e", then "-es" is added: "buzz" → "buzzes"; "catch" → "catches". Verbs ending in a consonant plus "o" also typically add "-es": "veto" → "vetoes". Verbs ending in a consonant plus "y" add "-es" after changing the "y" to an "i": "cry" → "cries".
