To Convey
To Tell, To Pass Down, To Transmit
transitive verb, ichidan verb
This word consists of kanji with hiragana attached. Because the hiragana ends with an う sound, you know this word is a verb. The kanji itself means transmit, but 伝える is mostly used for "transmitting" information, feelings, or messages to someone else. So it means to convey, to tell, or to pass down.
In technical contexts, 伝える can also mean to transmit, in the sense that copper transmits heat or air transmits sound.
