The phrase "A bas le les" is a French expression meaning "down with the them." Despite having a seemingly inconsistent spelling, the word is pronounced as "ah bah lay lay." This can be explained through the International Phonetic Alphabet (IPA) transcription, where "A" is pronounced as "ah," "bas" is "bah," "le" as "lay," and "les" as "lay." Although this phrase may be tricky to spell at first, understanding its correct pronunciation in French can make it easier to grasp.
