In plain English: To inform someone means to tell them facts or news so they know something important.
"He informed his boss about the meeting cancellation."
Usage: Use "inform" to mean giving someone specific facts or details about a situation, not to teach them a skill or subject. It is incorrect to use this word when you intend the meaning of training or educating someone.
Without regular form; shapeless; ugly; deformed.
"The storm left the coastline in a rough and inform state, stripping away all traces of its once orderly structure."
"I am not in an informed position to answer that question."
Usage: The word "inform" is strictly a verb and cannot be used as an adjective to mean shapeless or ugly. To describe something without regular form, you must use the adjective "informal," though this typically refers to casual style rather than physical deformity.
The word "inform" entered English from Old French and originally meant to shape or train someone. It comes from the Latin phrase for putting something into a specific form, reflecting its early sense of instructing rather than just giving news.
