immo, "same one, self" (VT49:33), general singular reflexive pronoun (covering both the 1st, 2nd, and 3rd person sg.), except where the subject is impersonal, in which case imma is used instead (VT47:37). Hence *tirin immo* "I watch [my]self", tirilyë immo "you watch [your]self", tiris immo "(s)he watches [him/her]self" (but apparently tiris imma** "it watches [it]self").

A pronoun for the “same one [person], self” in notes from 1969, also functioning as a personal reflexive pronoun (VT47/37; VT49/21), in one place given as imme (VT47/38). It is a combination of im- “same” and mo “someone”. It appeared in initial drafts of the Ambidexters Sentence from around this time: an ke mo querne immo numenna “✱for if one turned oneself towards the West...” (VT49/6). This word is also mentioned in 1969 notes on the definite article, where it had the gloss “the same person” and replaced more ancient ✱imo (PE23/135).
Conceptual Development: Demonstrative, Relative, and Correlative Stems (DRC) from 1948 had ᴹQ. one “the same person” based on ᴹQ. on- “same”, originally given as {alare >> alware >> alasse} (PE23/103 and note #44).
