hokutō. This is further complicated by the fact that many kanji have more than one on'yomi: is read as sei in sensei "teacher" but as shō in isshō "one's whole life". Meaning can also be an important indicator of reading; is read i when it means "simple", but as eki when it means "divination", both being on'yomi for this character. These rules of thumb have many exceptions. Kun'yomi compound words are not as numerous as those with on'yomi, but neither are they rare. Examples include tegami "letter", higasa "parasol", and the famous kamikaze "divine wind". Such compounds may also have okurigana, such as (also written ) karaage "Chinese-style fried chicken" and origami, although many of these can also be written with the okurigana omitted (for example, or ). In general, compounds coined in Japan using japanese roots will be read in kun'yomi while those imported from China will be read in on'yomi. Similarly, some on'yomi characters can also be used as words in isolation: ai "love", Zen, ten "mark, dot". Most of these cases involve kanji that have no kun'yomi, so there can be no confusion, although exceptions do occur. Alone may be read as kin "gold" or as kane "money, metal"; only context can determine the writer's intended reading and meaning. Multiple readings have given rise to a number of homographs, in some cases having different meanings depending on how they are read. One example is , which can be read in three different ways: jōzu (skilled), uwate (upper part), or kamite (stage left/house right). In addition, has the reading umai (skilled). More subtly, has three different readings, all meaning "tomorrow": ashita (casual), asu (polite), and myōnichi (formal). Furigana (reading glosses) is often used to clarify any potential ambiguities. Conversely, in some cases homophonous terms may be distinguished in writing by different characters, but not so distinguished in speech, and hence potentially confusing. In some cases when it is important to distinguish these in speech, the reading of a relevant character may be changed. For example, (privately established, esp. school) and (city established) are both normally pronounced shi-ritsu; in speech these may be distinguished by the alternative pronunciations watakushi-ritsu and ichi-ritsu. More informally, in legal jargon "preamble" and "full text" are both pronounced zen-bun, so may be pronounced mae-bun for clarity, as in "Have you memorized the preamble [not 'whole text'] of the constitution?". As in these examples, this
