Syntax/word order of ASL?
Sign language is mindblowing to me because it makes use of both time and space while spoken language mainly comes out as a linear string of sounds. Signers have a set of hands and countless facial expressions to work with during a single instance of time, and the hand sign/expression can be held/moved for multiple instances while the sentence continues itself.
But what does that look like in syntax, specifically for ASL? How would you draw a tree for a sign that is held continously? More importantly, compared to spoken languages, is ASL word order actually more flexible, or is there just a lot more movement going on within the SVO structure? I so far have been assuming the former because I imagine sign languages are more flexible by nature (due to the characteristics mentioned above).
(And so far the movements I've looked into have been DP movements that also exist in spoken languages e.g. topicalization)
