artichoke

English artichoke comes from Lombard articioch, itself from Occitan artichaut, from Old Spanish alcarchofa, from Andalusian Arabic al-ḵaršúf, the definite form of Arabic al-ḵuršūf.

The word passed from Arabic through Andalusian Arabic into Old Spanish, then Occitan, then Lombard, before finally settling into English — each language reshaping its sound along the way.

The facts given don't support tracing this word to any other English cognate.
