The pronoun base /idam- (cognate to Latin idem) means "this".
It loses m ?? by tyadAdInAmaH and atoguNe, and loses id इद् by halilopaH (72113).
So it only keeps all its letters when the /sup is deleted, and, as /idam- is never used ibc, that only happens before /su /am when neuter —
idam- n + /su OR /am → !**idam इदम् "this" by svamornapuMs...
