The word "LLER" may seem unusual to English speakers, but it is a valid spelling in Spanish. In IPA phonetic transcription, "LL" is pronounced as a voiced palatal lateral approximant [ʎ]. This sound is similar to the "y" sound in "yes". "ER" is pronounced as a voiced alveolar approximant [ɾ], which is similar to the "tt" sound in "butter". When put together, "LLER" is pronounced as [ʎeɾ], with emphasis on the first syllable.
