Some words do not have direct opposites [antonyms]. The word "but" has no antonym. (head) ↑ I am not sure why the word "head" is in brackets....if someone is indicating that "head" is an antonym for "but", they are incorrect. "Butt", as in derrière, is spelled with two "tt"s; "B-U-T-T"
front, head
toe
A synonym for nodded is acknowledged. An antonym for nodded is shook his/her head (meaning "no").
the answer is speak because your thought is in your mind or head but when you speak its saying what your thought is.
profile means the side view of the head so an antonym must me front view.
The antonym for the verb pre-position would be post-position. The part of speech "preposition" does not have an antonym.
To draw is a good antonym for the word "visualize " because you are not thinking supposed to draw it, but think about a picture in your head. #Hopethishelped
"Necktie" does not have an antonym, exactly. Perhaps "shoelace," designating a knotted fabric at the opposite extremity from the head and neck, is what you seek.
Off the top of my head, 'absorb' comes to mind...
