For every language there is a tense that is morphologically closest to the root, e.g. English present is more basic than perfect since perfect either adds a suffix -(e)d or has ablaut as tense marker. Is there a language where some verbs (simplistically "verbs with perfective semantics [VPS]") such as find, come, say are unmarked in preterite, the perfective tense, and marked in present, the imperfective tense; whereas other verbs, those "with imperfective semantic tense" (VIS) such as search (for), walk, talk (about) are marked in the preterite and unmarked in present? E. g.
nenden ("walk") > pres. nen, pret. nendud ("walked").
niden ("vanish, go away") > pres. nidun, pret. nid
(I suppose English has monosyllabic preterite forms for VPS such as put, cut for phonological reasons (unchanging ablaut of verbs with stem vowel u) not because the verbs are VPS. Ancient Greek had a very basic past tense in the aorist, arguably more basic with the VPS twin of verb roots such as peithō, cf. epithon (perfective: "persuade") vs. epeisa ("woo").)
