A row is a fight, though it's pronounced in a way I can't seem to type phonetically. But not like row of corn or row the boat.
It can be pronounced like "grow" and like "how" (or "bough".)
Take a bow with your bow tie on.
Pile up a mow when you mow down your hay.
Have a row when the row is not straight.
Tie up the sow when you sow seeds.
That tow-headed man drives a tow truck.
(For additional fun, pronounce bough, cough, rough, and tough.)
Rhymes with "how".
