Common mistakes'Likely' vs 'likelihood': Confused the adjective with the noun., 'Likely' placement: Wrongly placed before the verb instead of before 'to'., 'Unlikely' usage: Misusing 'unlikely' in positive contexts.Used in informal situations where a casual word would be better., Confused with 'presume', which has a different grammatical structure., Overused in statements where certainty is needed.
Usage notesUse 'likely' to express probability in neutral contexts. Avoid in very formal writing; use 'probable' instead. For informal contexts, 'likely' is suitable.Use 'presumably' when you think something is true but don't have definite proof. It’s more formal than using 'probably' and is often used in writing or serious conversations.
