Page "Word" Paragraph 14

Vietnamese orthography, although using the Latin alphabet, delimits monosyllabic morphemes, not words.

East Asian orthographies ( languages using CJK characters ) also tend to delimit syllables ( in the case of Chinese characters ) or morae ( in the case of kana ) rather than full words.

Hangul the Korean alphabet, delimits both syllables and words, by grouping graphemes into syllabic blocks but also adds spaces between words.

Conversely, synthetic languages often combine many lexical morphemes into single words, making it difficult to boil them down to the traditional sense of words found more easily in analytic languages ; this is especially difficult for polysynthetic languages, such as Inuktitut and Ubykh, where entire sentences may consist of a single word.
