conjunction
also, too
A1
'auch' means 'also' or 'too', used to add or emphasize additional information. Grammatically listed here as a coordinating conjunction, it commonly appears near the element it modifies (often after the verb or subject). Not reflexive, requires no auxiliary, and doesn’t govern case or prepositions.

Details
Mnemonics
Imagine adding one more item to a list with a little plus sign → that addition is 'auch' (also/too).
sounds like English 'ouch' but with an extra 'a' at the front — 'auch' often tags an extra idea (also/too).
Notes
‘auch’ is very common and flexible — used to add information (also) or to agree (too). It can combine with other particles (z. B. 'auch nicht').
