Undercurrent is a word that describes something that is happening secretly or without being noticed. It can also refer to a hidden feeling or emotion that is present in a situation. For example, in a conversation, there might be an undercurrent of tension or suspicion between two people that they are not openly discussing. In a river, there might be an undercurrent that flows beneath the surface and can be dangerous to swimmers. The word undercurrent can be used in many different contexts, but it often implies that there is more going on than what is immediately visible.
