# end-
## English
### Alternative forms

* endo-
* ento-

### Etymology

From the Ancient Greek ἔνδον (éndon, “within”).

### Pronunciation

* (Received Pronunciation) enPR: ĕnd, IPA: /ɛnd/

### Prefix

end-
* internal, within, inside, into

#### Usage notes

* When combined with a term beginning with a consonant, end- concatenates with the interfix -o- (as endo-).
* The prefix end- is usually stressed in the terms it forms (as in endoscope: ĕnʹdōskōp); however, it is never stressed when stress falls on the following syllable (as in endoscopy: ĕndŏʹskŏpi), and stressing the prefix is optional when the subsequent syllable is stressed (as in endoscopic: ĕndōskŏʹpĭk or ĕn'dōskŏʹpĭk).

#### Synonyms

* (inside): in-, intra-, en-/em-/im-, endo-/ento-

#### Antonyms

* (antonym(s) of “inside”): out-, ex- exo-, ecto-
