- -ö- (clarifies pronunciation, very rare)
語源 1
Adopted from Latin -o-, originating ultimately from Ancient Greek -ο- (-o-). In English, the connective is found from the 中期英語 period in direct borrowings from Latin. Direct formations of English terms with the connective, always combining Greek or Latin roots, appear from the 16th or 17th century. From the 18th century, the suffix becomes productive in compounds where the second element is English. From about 1800, formations on all sorts of stems become common.
接合辞
-o-
- A linking vowel inserted interconsonantally between two morphemes, to ease pronunciation, without contributing to the meaning. It frequently joins words or combining forms of Ancient Greek or Classical Latin origin in the classical compounds of New Latin and international scientific vocabulary, but it can also be used to join modern terms and even abbreviations, either formally or informally.

語源
Adopted from the thematic vowel in Ancient Greek -ο- (-o-), often used to form nominal compounds. In Ancient Greek, the connective suffix originates in compounds where the first member is thematic, such as δημοκρατία (dēmokratía), but was extended by analogy to other stems, such as μητρόπολις (mētrópolis). The suffix was borrowed as a connective into Latin, mainly in compounds of Greek origin.
The suffix becomes productive and forms new compounds in learned humanist Latin, from the Renaissance. The connective is especially productive in connecting ethnonyms or geographical terms; genuine Greek stems include Gallo-, and Syro-, but most are of medieval or modern origin, productive from the 15th century, such as Anglo-, Graeco- or Latino-.
