XX, or x, is the 24th and third-to-last letter in the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is "ex" (pronounced 'ɛks), plural exes. In Ancient Greek, 'Χ' and 'Ψ' were among several variants of the same letter, used originally for /kh/ and later, in western areas such as Arcadia, as a simplification of the digraph 'ΧΣ' for /ks/.
MorphophonologyMorphophonology (also morphophonemics or morphonology) is the branch of linguistics that studies the interaction between morphological and phonological or phonetic processes. Its chief focus is the sound changes that take place in morphemes (minimal meaningful units) when they combine to form words. Morphophonological analysis often involves an attempt to give a series of formal rules or constraints that successfully predict the regular sound changes occurring in the morphemes of a given language.
Dual-route hypothesis to reading aloudThe dual-route theory of reading aloud was first described in the early 1970s. This theory suggests that two separate mental mechanisms, or cognitive routes, are involved in reading aloud, with output of both mechanisms contributing to the pronunciation of a written stimulus. The lexical route is the process whereby skilled readers can recognize known words by sight alone, through a "dictionary" lookup procedure. According to this model, every word a reader has learned is represented in a mental database of words and their pronunciations that resembles a dictionary, or internal lexicon.
