On page 33 of the Lonely planet phrasebook for Japanese, 5th edition (ISBN 978-1-74104-231-3), the phrase given is
What does 'deguchi' mean?
The pronunciation guide has
de-gu-chi wa dō yū i-mi des ka
However, when I searched for "はどう意味ですか" (without いう or 言う to bias the search), I found most of the matches were for "いう".
Should I use "言う" or "いう"? Also, is use of "言う" or "いう" specific to this phrase, or is it normally written that way?
