“…As shown in the example below, of the two multicharacter words that share the initial character 非/fēi/, the former represents a monomorphemic word (非常, /fēicháng/,), while the latter corresponds to an affixed word (非-正式, /fēi-zhèngshì/, "in-formal"). Moreover, MA correlates highly with vocabulary knowledge because MA includes knowledge of morpheme functions, which makes it difficult to distinguish the two constructs and casts doubt on the validity of MA measurement (Ke & Koda, 2019;D. Liu, McBride-Chang, Wong, Shu, & Wong, 2013).…”
