Is there any shorthand way of identifying new words when reading the script.

As you know, because some letters don't connect to other letters, it seems difficult to know where a word ends and another word begins. See the word for "sometimes," ساعات or Sa3at. Ayen never connects at the beginning.

Or the word for nervous, متوترين, "metwattarin." Is it just memorization of words, or do you start to recognize what should be word endings to know to continue?
