The most common beginner mistake is also the most invisible one: signing English. You learn the sign for each English word, put them in English order, and mouth the English sentence. A Deaf person can usually decode it, the way you could decode a tourist saying "I want to the station go," but it is not ASL, and it never becomes fluent.
ASL is a separate language with its own grammar. Here are seven rules that change how you build every sentence, each with signs you can watch.
1. Time goes first
English can put time anywhere: "I went to the store yesterday." ASL sets the time at the start so the listener knows where on the timeline they are. YESTERDAY I GO STORE.
Once the time is set, you do not conjugate anything. There is no "went" versus "go." Yesterday tells you it was the past, and GO stays GO. The days and time guide covers the timeline.
2. Topic, then comment
ASL often puts the topic first, with raised eyebrows, then says something about it. English: "I don't like coffee." ASL: COFFEE, I DON'T-LIKE, with the eyebrows up on COFFEE and a slight pause. The topic is the frame; the comment fills it.
This is also why question words go at the end. YOUR NAME WHAT? sets up the topic (your name) and then asks about it.
3. There is no "is," "a," or "the"
English needs "I am happy." ASL is I HAPPY, or just HAPPY with a nod. "Are you Deaf?" is YOU DEAF? with raised eyebrows. Articles do not exist; "the car" and "a car" are both CAR. Beginners who hunt for a sign for "is" are looking for something that is not there.
4. The face is grammar
Raised eyebrows make a yes-or-no question. Lowered eyebrows make a WH-question. A head shake negates: I LIKE with a head shake means "I don't like," even without a NOT sign. Puffed cheeks make something big or far; pursed lips make it small or near.
None of this is optional and none of it is emotional decoration. It is the equivalent of word endings and auxiliary verbs in English. Our post on facial expressions goes deep.
5. Space is grammar
When you talk about someone who is not there, you give them a spot in the air. Point to the right for your sister; point to the left for your boss. From then on, pointing right means your sister. Verbs can move between the spots: GIVE moving from your sister's spot to your boss's spot means she gave something to him. One movement, whole sentence.
This is why He covers he, she, him, her, and it. The pronoun is a location, not a word.
6. Verbs change direction, not ending
English conjugates: ask, asks, asked. ASL inflects by direction: ASK moving from you toward someone means you ask them; moving from them toward you means they ask you. Same handshape, opposite meaning.
Help toward someone is "help you"; toward yourself is "help me." Tell from the chin outward is "I tell you." Learn the base verb and then practice pointing it.
7. Repetition and size carry meaning
Signing WALK once is "walk." Signing it with a slow, repeated motion is "walk for a long time" or "walk and walk." Signing it small and fast is "walk quickly." English uses extra words for all of that; ASL changes the sign itself. The same goes for intensity: a bigger, slower HAPPY is "very happy." There is a VERY sign, but fluent signers use it far less than beginners do.
Putting it together
English: "Are you going to the party tomorrow?" ASL: TOMORROW PARTY, YOU GO? with the eyebrows up at the end.
English: "I didn't understand what she said." ASL: SHE SAY, I UNDERSTAND with a head shake on UNDERSTAND and a point to her spot for SHE.
You do not have to master all seven rules before you sign. Pick one, time first, and use it every day this week. Then add the eyebrows. Then the topic-comment order. The grammar builds the way vocabulary does, one habit at a time.
