"Your point also"

THATTOO

Think of a casual agreement that sounds like it’s missing a letter at the end.

The clue "Your point also" is a playful way to hint at "THAT TOO." Break it down: "your point" sounds like "that" in casual speech (as in "I see your point—that makes sense"), while "also" directly means "too." Combine them, and you get "THATTOO," which is how the answer is written here—no space, just like in some crosswords for brevity. The wordplay relies on interpreting "point" as a conversational filler rather than a literal dot or argument.
