Some signs can show by their movement “who did what to whom”. The movement of the sign indicates the subject and object of the verb. For example, if I sign “money” and then sign “give,” starting with my body and moving the “give” sign in your direction, I sign “I`m going to give you some money” or “I gave you money.” Suppose I start the sign by avoiding my body sign (regardless of your direction), then moving the “give” sign towards me and ending near my body. It means, “You`re giving me some money.” When I look at you and move the “give” sign to the right or left, I sign “Give it”. This “directionality” can be used with many (but not all) characters. How do you know which ones? You connect with experienced users of the language and attack them, or you watch many videos of experienced signatories, or you attend many courses, you pay attention to them and you ask questions about the signs. They can diryscalize many different verbs. Hand-to is the best example, but “MEET” is also useful. [To sign MEET, keep both index fingers about one foot apart, pointed upwards, the palms of the hand turn towards the other. Then you put them together – it looks like two people meeting.
Note: The index fingers do not touch each other, only the lower parts of the hands.] For example, ME-MEET-YOU can be performed in a single movement. I don`t need to sign “I” “MEET” “YOU” as three separate words. But I hold my right index finger close to me, the palm of my hand towards you and my left index finger near you, the palm of my hand towards me. I will bring my rights to the left. One request was enough. A student asks: how do you know which verbs to use? Answer: This requires interactive exercise and learning. Some verbs are simply not indicative. Example: “WANT.” They sign “WANT” and separately indicate who wants what. For example, to sign “SHE WANT CANDY”, you would point to the little girl, sign “WANT” and then sign “CANDY”. (Just a marginal note: Although “WANT” is not “directional”, it uses another interesting ASL grammar function. WANT/DON`T-WANT is a great example of reversing orientation for negation.) Suzanne, well, first of all, I think you have to specify what kind of bending you`re talking about. The “arrowing” of a sign simply means changing or modifying the character.
I scratch my head to think of any sign (verb or not) that can`t be wilted in one way or another. I think you may want a list of verbs that can be withered (modified) to indicate the subject and/or purpose of the sentence. This is called “verb overestimation.” So what you may be looking for is a list of “matches” and a list of verbs that don`t show a “match”. Verbs can indicate the subject or object of a sentence by tilting the palm orientation of the hand (in which direction the palm of your hand points), the position of the sign, or both….
