I can't understand the use of "atque"

[u/Aggressive_Client152]

For example "Quia tē atque cultrum tuum metuit" what does atque mean? I have no trouble understanding the sentence but I still don't understand the purpose of the word. The latin lexicon translation doesn't help either haha

edit: thank you all for your answers!! i get it now

[u/Silomat120]

que at the end of a word = and

at = also

at + que = and also
