词根词缀:inter-, intero-

【来源及含义】Latin: between; among, mutually, together; on the inside, internal

【相关描述】Although abstracted from the many compounds in which it entered English, the form inter- was not generally considered a living prefix in English until the 1400s.

During the later period of Middle English many words borrowed in the Old and Middle French forms entre-, enter- began to be consciously respelled with Latin inter-; although vestiges of the older French borrowings are found in entertain and enterprise.

The living prefix inter- is now freely added to almost any element in English to create such formations with the meaning of "between" and "among". The words formed by intra- are closely related to this inter- prefix; in fact, they both apparently came from the same Latin source.

【相关词根词缀】 Related "together" units: com-; greg-; struct-. Cross references of word families related directly, or indirectly, to: "internal organs, entrails, inside": ent-; enter-; fistul-; incret-; intra-; splanchn-; viscer-.

词根词缀:mne-, mnem-, mnemon-, mnes-, -mnesia, -mnesiac, -mnesic, -mnestic

【相关词根词缀】 Etymologically related "forget, forgetfulness" word families: aletho-; letho-; oblivio-. Related "memory, remembering" word families: memor-; reminisc-.

【同源单词】acousmatamnesia, amnemonic, amnesia, amnesiac, amnesic, amnesiophobia

词根词缀:psych-, psycho-, -psyche, -psychic, -psychical, -psychically

【来源及含义】Greek: mind, spirit, consciousness; mental processes; the human soul; breath of life; literally, "that which breathes" or "breathing"

【相关描述】A prefix that is normally used with elements of Greek origin, psych- affects the meanings of hundreds of words.

Etymologically, this element includes such meanings as, breath, to breathe, life, soul, spirit, mind, consciousness.
