You could use a formula and count spaces
under datavalidation select custom,

=(LEN(B1)-LEN(SUBSTITUTE(B1," ","")))<=4

for 4 spaces e.g. 5 words, that means you can write

"The rain in Spain stays"

but not

"The rain in Spain stays mainly in the plain"

Thank you. But how about the WORD limit? I can only find text limit in
the
data validation.

Thanks much.
