|Look up homograph in Wiktionary, the free dictionary.|
A homograph (from the Greek: ὁμός, homós, "same" and γράφω, gráphō, "write") is a word that shares the same written form as another word but has a different meaning. However, some dictionaries insist that the words must also sound different, while the Oxford English Dictionary says that the words should also be of "different origin". In this vein, The Oxford Guide to Practical Lexicography lists various types of homographs, including those in which the words are discriminated by being in a different word class, such as hit, the verb to strike, and hit, the noun a blow.
If, when spoken, the meanings may be distinguished by different pronunciations, the words are also heteronyms. Words with the same writing and pronunciation (i.e. are both homographs and homophones) are considered homonyms. However, in a looser sense the term "homonym" may be applied to words with the same writing or pronunciation. Homograph disambiguation is critically important in speech synthesis, natural language processing and other fields. Identically written different senses of what is judged to be fundamentally the same word are called polysemes; for example, wood (substance) and wood (area covered with trees).
where the two words are spelt identically but pronounced differently. Here confusion is not possible in spoken language but could occur in written language.
where the words are identical in spelling and pronunciation, but differ in meaning and grammatical function. These are called homonyms.
|Word||Example of first meaning||Example of second meaning|
|lead||Gold is heavier than lead.||The mother duck will lead her ducklings around.|
|close||"Will you please close that door!"||The tiger was now so close that I could smell it...|
|wind||The wind howled through the woodlands.||Wind your watch.|
|minute||I will be there in a minute.||That is a very minute amount.|
Modern study of Old Chinese has found patterns that suggest a system of affixes. One pattern is the addition of the prefix /*ɦ/, which turns transitive verbs into intransitive or passives in some cases:

|塞||*sɨk||(v.) block||*sɨks||border, frontier|

Many homographs in Old Chinese also exist in Middle Chinese. Examples of homographs in Middle Chinese are:
|別||/bĭɛt꜆/||(v.) part||/pĭɛt꜆/||differentiate, other|
|上||/꜂ʑĭaŋ/||rise, give||/ʑĭaŋ꜄/||above, top, emperor|

Many homographs in Old Chinese and Middle Chinese also exist in modern Chinese varieties. Homographs which did not exist in Old Chinese or Middle Chinese often come into existence due to differences between literary and colloquial readings of Chinese characters. Other homographs may have been created due to merging two different characters into the same glyph during script reform (See Simplified Chinese characters and Shinjitai).
Some examples of homographs in Cantonese from Middle Chinese are:
|上||[ɕœːŋ˩˧]||rise, give||[ɕœːŋ˨]||above, top, emperor|
