English is a diverse language, well known for borrowing and stealing from other languages - including Welsh.

The development of English was greatly influenced by the vocabulary of invaders, both Norse and Norman.

But linguistic experts believe it may have also borrowed a few words from Welsh and its ancient ancestor language.

According to Wales Online modern Welsh is believed to be from the ancient language of the Britons who inhabited Great Britain, believed to have arrived on the island during the Bronze or Iron Age.

Here are 10 common English words that some linguists believe may have been influenced by Welsh:
