              American English
              
                - IPA Pronunciation: /ˈʌndərˌlaɪɪŋ/
 
                - Respelling: UHN-der-ly-ing (with "UHN" as a schwa sound like the 'u' in "fun," "der" as in "her," "ly" rhyming with "lie," and "ing" as in "ring")
 
              
              British English
              
                - IPA Pronunciation: /ˈʌndəlaɪɪŋ/
 
                - Respelling: UHN-der-ly-ing (similar to American English, with "UHN" as in "fun," "der" like in "her," "ly" as in "lie," and "ing" as in "ring")
 
              
              In both dialects, "underlying" is pronounced with the primary stress on the first syllable "UHN." The word begins with "UHN," a schwa sound similar to the 'u' in "fun," followed by "der," which sounds like "her," then "ly," rhyming with "lie," and concludes with "ing," as in "ring." The pronunciation is consistent between American and British English.
              Etymology
              The term "underlying" is derived from the combination of "under-", meaning "below or beneath", and the verb "lie", meaning "to be situated". Historically, it refers to something that lies beneath or is the foundation or basis of something else.
