Crossword Genius

Tack in three directions (3)

Ross

I believe the answer is:

sew

This clue is a double definition.

'tack' is the first definition.
(I know that tack is a more specific form of sew)

'three directions' is the second definition.

'in' is the link.

(Other definitions for sew that I've seen before include "Stitch with needle and thread" , "Tack" , "Fasten with needle and thread" , "Work with needle and thread" , "Fasten with stitches" .)

I've seen this clue in The Times.
