并列主语后的谓语动词是否为第三人称单数取决于该主语是否为同位并列。然而，在英语习语Timeandtidewait（s）fornoman中，同位并列主语后仍不能有屈折词缀一s。这是因为古英语谚语多用虚拟语气。而同是以timeandtide作主语的其它句子，由于本身不是英语习语，谓语动词就应该为第三人称单数。 Whether the predicate verb after the collocated subject is the third person singular depends on whether the subject is in the same position or not. However, in the English idiom Timeandtidewait (s) fornoman, there is still no inflectional affiliation after the collocated subject. This is because the old English idioms are mostly subjunctive. The same is timeandtide as the subject of other sentences, because they are not English idioms, the predicate verb should be singular third-person.
