Topicalization using an OSV (Object Subject Verb) structure in American Sign Language (ASL) is very common. Although, not all ASL sentences are structured as OSV. There are some SVO (Subject Verb Object) sentences where fit.
Gloss: /\GREEN CAR/\ I REMEMBER.
English equivalent: I remember the green car.
While signing the object (GREEN CAR), raise eyebrows as well as slighting tilting forward the head. Another example:
/\CAT IX1/\ DOG(IX2) BITE(IX1). IX1 and IX2 represent spatial references.
These are a few examples of numerous OSV-structured sentences. In addition to some examples above, you'd see a plenty of OSV sentences in the ASL dictionary on this website.
Also see SVO sentence structure (Subject-Verb-Object).
These are some ASL lessons, tutorials, and tips that ASL students and language enthusiasts can explore and learn some ASL on their own relaxing pace.
Seeking some challenges? Try some stories, fables, and others in ASL storytelling and poetry. Study a complex system of subtle eye gazes, role-shifting, classifiers, sentence structures, and other linguistic features as well as poetics.
