OA lyšh; OfA lˀ ˀyt, lˀyt, lˀyty; Syr. always ܠܲܝܬ܂܂‏; JLA in conjunction לֵית but, e.g., לָיְתֹוהִי with sg. pronominal suffixes (while the /ē/ vowel is preserved before pl. sufixes where it is two syllables before the stress) and in disjunction simply לָיִת ; Sam. with pron. suf. ליתך, ליתו, ליתן etc., but later ליני, לינך; Qum. also written separately

See also s.v. mdlyt.

All dialects would seem to allow lyt before independent personal pronouns, but the combined forms are somewhat more limited in distribution to the more post-literary strata. On the early examples of this composite form see now E.M.Cook in H. Drawnel, ed. STSJ 216: pp. 39f.
