lamba
hammer
lamba (2) noun ?"hammer" (possibly an alternative form of namba, q.v., but the source is obscure and namba is to be preferred) (VT45:37)
namba
hammer
namba noun "a hammer" (NDAM), namba- vb. "to hammer" (NDAM). According to VT45:37, Tolkien may have considered the alternative form lamba, but the source is obscure and lamba is assigned a quite different meaning ("tongue") elsewhere.
amu
up, upwards
amu adv. "up, upwards" (LT2:335; in Tolkien's later Quenya amba)
am-
up
am- (1) prefix "up" (AM2)
am-
prefix. up, up, [ᴱQ.] upwards
A prefix for “up”, very well attested and derived from √AM of the same meaning (Ety/AM²).
Conceptual Development: The Qenya Lexicon of the 1910s had ᴱQ. am(u)- “up(wards)” reflecting the earliest form of the root ᴱ√AM(U) (QL/30), but by the 1920s the u was dropped (PE16/75), and it was only am- thereafter. In Tolkien’s later conception, it probably became ama- when seperation from a following consonant or cluster was needed (PE17/92), as in ᴹQ. amatikse “above dot” (Ety/TIK).
lil
more
lil adverbial particle "more" (PE14:80)
An adverb for “up(wards)” derived from the root √AM “up” (PE17/157; Ety/AM²). In one place Tolkien said it “is generally limited to the qualification of words signifying or implying motion: especially ‘rise, ascend, climb, grow etc.’ (PE17/91)”, but that was not the case in (for example) Ambarussa “Top-russet” (PM/354), so this rule was not universal.
Conceptual Development: The Qenya Lexicon of the 1910s had ᴱQ. amu “up(wards)” reflecting the earliest form of the root ᴱ√AM(U) (QL/30), but by the 1920s it was amba “up” (PE13/137; PE16/62), a form that was retained thereafter. In one place in The Etymologies of the 1930s Tolkien gave it an alternate form ama beside amba (Ety/UNU), but since this was as an element in ᴹQ. amatikse “above dot” (Ety/TIK; EtyAC/UNU) I think it is more likely a variant of prefixal am- “up”.
