true / real / really

This sign can be used to mean many English concepts such as: Sure, indeed, absolutely, "you're welcome," real, really, very, etc...

The sign for "true" is made by placing the right index finger against your lips. Your palm should face left.

Move your finger forward about 7 inches using a quick motion. The tip of the finger ends up a couple inches further forward than the base of the index finger.

Note:

ASL doesn't use specific signs for "state of being" verbs: is, am, are, be, being, been, was, and were. Signed English uses these signs, but ASL doesn't.

Note: although ASL doesn't use "be" verbs, the sign for "true" is often used to affirm the existence or reality of something.

If you wanted to say, "I am happy" in ASL you would simply sign,
"I HAPPY"
while nodding your head.

You wouldn't need to sign "I TRUE HAPPY."

If someone questioned you and said, "I THINK YOU LIE!" You could affirm that you are truly, indeed happy by signing, "FINIISH-(one hand) I TRUE HAPPY!" Which would mean "Oh knock it off, I really am happy!"
