cell B1 contains a word listed in cell A1

[Stan]

Is there a formula to use in order to confirm the following?

If a sentence in cell B1 contains a word in cell A1, confirm it in cell C1.
Words in column A is changing cell-by-cell.

thanks for yoru help.

Case-sensitive:
=FIND(A1,B1)
Non-case-sensitive
=SEARCH(A1,B1)

Your specifications are not entirely unambiguous, but perhaps something like:

=IF(AND(LEN(A1)>0,ISNUMBER(SEARCH(A1,B1))),"Contained","Not Contained")
