The word "heartbeat" is derived from the combination of two terms: "heart" and "beat".
The term "heart" can be traced back to the Old English word "heorte", which was derived from the Proto-Germanic word "*hertô". This word is believed to have originated from the Proto-Indo-European root "*kerd-", meaning "heart".
The word "beat" comes from the Old English word "beatan", which meant "to strike" or "to hit". It is closely related to the Proto-Germanic word "*bautan", which has the same meaning.
When these two words are combined, "heart" refers to the organ that circulates blood, while "beat" refers to the rhythmic pulsation or contraction of the heart. So, "heartbeat" essentially means the pulsation or rhythm of the heart.
