There seem to be a lot of highly technical dissertations on the
subject out there. Here are a few plain examples that might help you
get your mind around the concept. I think the multi-directional verbs
are ones that can be used in either direction such as the sign for
give. I.e. you give to me or reversed, I give to you.
Uni-directional would be those that only work in one way such as sit.
Good luck.

Within ASL there is a class of directional verbs. These include the
signs for pay, give, show, invite, send, and several others. Depending
on which way the hand moves, either away from the body or towards,
distinguishes between the subject and object of the sentence, which
are both included within the one sign. For example, to sign "I GIVE
YOU", the hand in the shape of a flattened "O" moves away from the
signer's body. In signing "YOU GIVE ME" the same handshape is drawn
toward the body. Directional verbs may also interact with the noun
locus system; for instance, one might set up "DOG" and "CAT", and then
convey "DOG BITE CAT" by signing "BITE" starting at the locus for
"DOG" and moving to "CAT". (From www.wikipedia.com) |
