What is the word for fart in Middle English?

Excuse me, I'm trying to research an interesting aspect of language evolution. Could you please tell me what the word for 'fart' would have been in Middle English? I'm fascinated by how vocabulary changes over time and am particularly interested in this particular bodily function. I'm aware that language can be quite nuanced and that there may be multiple terms or phrases used to describe it, so I'm open to any suggestions you may have. Thank you in advance for your assistance with this inquiry.
