preterite present verb造句

Among the primary innovations in Proto-Germanic are the preterite present verbs, a special set of verbs whose present tense looks like the past tense of other verbs and which is the origin of most modal verbs in English; a past-tense ending ( in the so-called " weak verbs ", marked with "-ed " in English ) that appears variously as / d / or / t /, often assumed to be derived from the verb " to do "; and two separate sets of adjective endings, originally corresponding to a distinction between indefinite semantics ( " a man ", with a combination of PIE adjective and pronoun endings ) and definite semantics ( " the man ", with endings derived from PIE " n "-stem nouns ).
