Words Starting With "M"
Our pre-recorded sounds are fast, clear, and natural, spoken by native speakers.
Methought
Methought is an archaic or poetic way of saying "I thought" or "I perceived". It is used to express a thought or an idea that occurred to the speaker at a previous time. The word "methought" is a first person singular past tense of the verb "to think", but it is often used in a more formal or literary context.
