Which language contributed many words related to art and crafts after the Norman invasion?

The correct answer is French because after the Norman invasion in 1066, the English language experienced significant influence from Norman French. This cultural and linguistic shift introduced a wealth of vocabulary into English, particularly in areas related to governance, law, art, and crafts, where French was the dominant language among the ruling class and artisans.

Art and craft-related terms are particularly notable because the Normans brought with them not just their language but also their customs and practices in these fields. As a result, many French words became integrated into English, enriching the language in various artistic domains such as painting, sculpture, and architecture. Examples include words like "palette," "decorative," and "finesse," all deriving from French, which became commonly used in English to describe artistic concepts.

The other languages listed—Celtic, Latin, and Greek—while influential in their own rights, did not have the same level of impact on English vocabulary specifically related to art and crafts during this period. Latin influenced many academic and ecclesiastical terms, Greek contributed to scientific and philosophical vocabulary, and Celtic had a more limited role in the broader development of English lexicon during and after the Norman invasion.
