שנימ

Based on the root word sen, the literal meaning of 'Senim' is “teeth” or “the Toothy Ones”. However, this appears to be an idiom whose actual meaning is “years”. This is interesting since the closely related word, seneh does appear to mean a time period, possibly a year. Therefore it seems likely that 'senim' may be a misspelling and shortening of senehim.

'senim' should not be confused (but often is)¹⁾ with seni (meaning “two”)
