The word "thoughtful" describes a person who shows consideration for the feelings of others or is reflective and pensive about things. Being thoughtful often means being kind, empathetic, and aware of how one's actions or words affect those around them. It can also refer to someone who gives careful thought to a subject or situation.
The word "thoughtful" originates from the combination of "thought," which comes from Old English "þoht," meaning "an idea, a concept," and the suffix "-ful," meaning "full of." Thus, "thoughtful" essentially means "full of thought" or "having many thoughts."
