If you ask a person how they are doing and they say "Regular" that means the same as saying "OK".
My native language is spanish, and I have never seen that word before! But, I suspect you mean either "irregular" which means not regular, or "arreglar" which means fix, repair.
Ser = to be
soy/eres/es/somos/sois/son = I am/you are etc.

I think what you mean is "What is the Spanish word for let?" because the word "let" is an English word, not Spanish. The Spanish word for "to let" is permitir. "Let me" is "permítame."
