词源说明
From Middle English -es, -is, from Old English -es, -as, Northern variants of -est, -ast (second person singular indicative ending). Replaced Middle English -eth, from Old English -eþ, -aþ. The falling together of the second and third person singular verb forms in Old English is believed to be due to Scandinavian influence, where the employment of the same verbal endings for both 2nd and 3rd singular indicative follows a similar pattern to that seen in Old Norse (e.g. þú masar, hann masar; þú þekkir, hann þekkir; etc.).
