When speaking with non-native speakers try to avoid using?
Avoid using contractions or short forms.
Use long forms. “Can't” is one word you must use the long form with. It is difficult for a non-native speaker to understand the difference between “can” and “can't” in a sentence. For example, “I can't take you on Friday” and “I can take you on Friday”.
Who are non-native speakers?
Non-native speakers of a language, on the other hand, are people who have learned this particular language as second or third language, but have a different language as native language.
