to get to know: perhaps *istanta/isinta-? eldamo.org - Eldamo : Middle Quenya : -nta

- "Recognize" can be expressed with "remember (X by/from something)".
- Q #cav- as meaning both "receive" (VT47) and "be able to" (PE22) semi-parallels Finnish saada (1. get, obtain; 2. be allowed, may).

+ܤܡܝ ܦܠܕܢܝܘܤ that's an interesting parallel but I somehow doubt that it was intentional; but one never knows with Tolkien!

+Tamas Ferencz See Eldamo's note on nta:
s “inceptive (verbal suffix)” maybe replaced ᴹQ. nta “to become or be made”-

ninqinta >?> ninkwis | both mean "to grow pale"

+Ekin Gören "maybe"

Having said that, I am fine with *istas-, too.

ninquis- (niñkwis- "(begin to) grow pale" PE22/135), seems to be an inceptive form of the inceptive ninquinta- (niñqinta- "to grow pale" PE22/114). So, istas- (begin to) get to know, would/could be the inceptive of istanta- to get to know. But that's how I read it from PE22.

Regarding "surprise" (to act surprisingly) : The Q descendant of http://eldamo.org/content/words/word-2808978273.html would be *verehta-. (Compare Hebrew hiphtiiaʕ < p-t-ʕ.)

Not bad. I recall years ago I used *verehta- for "explode".

+Tamas Ferencz There's apparently also this item. eldamo.org - Eldamo : Early Quenya : kapta-¹

+ܤܡܝ ܦܠܕܢܝܘܤ good find. It makes sense as "make jump"

HKF used atsintë for pa.t. of "recognize". I suspect pres.t. is atista-.

As for "to get", I am satisfied with EQ. ^ñet- QL:66
