Non-adjacent form is a way of writing a sentence that leaves out words that aren’t necessary. It also helps keep a sentence short and clear. To make a sentence non-adjacent, you would leave out words like prepositions (words including 'in', 'on', 'over', 'with' etc.), articles (e.g. 'the', 'a', 'an') and conjunctions (e.g. 'and', 'but', 'so'). For example, instead of writing "I went to the store with my friends," you could write "Went store friends." It's like playing a game of pick-up-sticks - you try to leave out as many words as possible without changing the meaning of the sentence.
