Search two values in a single cell and return the position of the first one found

I have a column in Google Sheets where every cell in that column contains two words, i'm looking for some formula to extract only the first word, knowing that sometimes there is space between the two words and sometimes there is back to line instead of space.

I have tried this :
=LEFT(C3180, FIND(" ", C3180)-1)
And it worked in cells where there is a space between the two words.

I also tried this :
=LEFT(C3180, FIND(CHAR(10), C3180)-1)
And it worked in cells where there is back to line between the two words.

Finally i have tried this but it doesn't work :
=LEFT(C3180, FIND(OR(" ",CHAR(10)), C3180)-1)

Here's one approach:

=regexextract(A2,"(.*)(?: |\n)")

You can try -in each cell- either of

=REGEXEXTRACT(B2:B31,"[a-zA-Z]+")

OR

=REGEXEXTRACT(B2:B31,"[[:alpha:]]+")

On the other hand, one can use a single formula for a whole range

=INDEX(IFERROR(
    REGEXEXTRACT(B2:B31,"[a-zA-Z]+")))

(Do adjust each formula according to your ranges and locale)
