I'm not sure if "aggr-" is a prefix but I can see some words starting with it. like:

  • Aggregate

  • Aggressive

  • Aggravate

  • Aggrieve

  • Aggrandize

I'm here to ask if it has some meanings or they are all started with "aggre-" by chance.

    Word 1: aggregate - from Latin aggregat- ‘herded together’, from the verb aggregare, from ad- ‘towards’ + grex, greg- ‘a flock’. Word 2: aggressive - from Latin aggress- ‘attacked’ (from the verb aggredi) + -ive. You can do the rest for yourself by googling [word] etymology, but obviously the first two are different.

  • Aggr- is not a prefix. You can easily verify that by trying to append it to any word at all. It will not work. Ever. While the whole job of a prefix is to be easily appendable to any number of words as long as they fit the bill of that particular prefix. No word at all can fit the bill of aggr because it has no bill.

  • (1) So perhaps the answer (from FumbleFingers) is: aggr- is not a prefix. If we have a prefix here it is the Latin prefix ad- which changes to ag- when it precedes a g. (2) Alternate answer: nowadays, agri- is a short form of agriculture so we do, indeed, say things like agribusiness. Yes, here it seems to act as a prefix. So aggr- is not a prefix, but agri- is.

    What is "unclear" here? Everyone may not be as much a pandit as the close voters.

No, aggr- is not a prefix. Latin had a prepositional prefix ad- that turned into ag- before g-. In the course of French's development from Latin, the preposition ad and the prefix ad- lost their final consonant sound. But French words formed with that prefix were sometimes spelled with doubled consonants in imitation of Latin practice (but not always: see fdb's answer to Why does “agree” have only one “g”?).

The aggr- sequence in all of the words that you list was originally formed by adding the Latin prefix ad- (ag-) or the French prefix a- (ag-) to bases starting with gr-. Aggrieve has the same etymological base as aggravate (the ie in aggrieve is from a French sound change).

The bases of the other words (grand-, greg-, gress-) go back to separate Latin roots. Although their pre-Latin etymologies seem a bit uncertain, I don't know of any proposals for etymologies that connect any of these roots.
