lye

thou/thee, you

lye pron. "thou/thee, you", 2nd person sg. formal/polite (corresponding to familiar/intimate tye, q.v.) (VT49:36) It seems the original stem-form was le (VT49:50), distinct from de as a plural "you", but when initial d became l and the forms threatened to fall together, le was apparently altered to lye by analogy with the ending -lyë and the emphatic pronoun elyë. Stressed lyé (VT49:51). For lye as object, cf. nai Eru lye mánata "God bless you" (VT49:39). Allative lyenna "to you, upon you" (VT49:40-41). Compare the reflexive pronoun imlë "yourself, thyself", q.v. (it did not have to be *imlyë, for the corresponding pl. pronoun indë "yourselves" is distinct anyhow).
