In the context of Hanyu Pinyin, Yaan can be considered a misspelling of Ya'an. In theory, a syllable-dividing mark (隔音符號／隔音符号 (géyīn fúhào)) should be added before a non-initial syllable beginning with a, o, or e. Hence, Yaan is not allowed since a word made up of ya and an would be spelled as Ya'an (cf. Ya'an). In practice, syllable-dividing marks are often added or omitted at will.
