• Webster's Revised Unabridged Dictionary
    • Ex- A prefix from the latin preposition, ex, akin to Gr. 'ex or 'ek signifying out of out proceeding from. Hence, in composition, it signifies out of as, in exhale, exclude; off from, or out, as in exscind; beyond, as, in excess, exceed, excel; and sometimes has a privative sense of without, as in exalbuminous, exsanguinous. In some words, it intensifies the meaning; in others, it has little affect on the signification. It becomes ef- before f, as in effuse. The form e- occurs instead of ex- before b d g l m n r, and v, as in ebullient, emanate, enormous, etc. In words from the French it often appears as es-, sometimes as s- or é-; as, escape, scape, élite. Ex-, prefixed to names implying office, station, condition, denotes that the person formerly held the office, or is out of the office or condition now; as, ex-president, ex-governor, ex-mayor, ex-convict. The Greek form 'ex becomes ex in English, as in exarch; 'ek becomes ec, as in eccentric.

    • ex- A Latin preposition, meaning ‘out,’ ‘out of.’ It is used in English only in certain commercial formulas, as— “20 chests tea ex Sea-King,” where ex means taken out of or delivered from the vessel named;
    • ex- A prefix of Latin, and in some cases of Greek origin, meaning primarily ‘out,’ ‘out of.’ In English words it preserves or reproduces its particular uses in the language of its origin. (See etymology.) Thus, in exclude, exhale, etc., it signifies ‘out,’ ‘out of’; in exscind, ‘off’; in exceed, excel, etc., ‘beyond.’ It is often (especially in the reduced form e-) simply privative, as in exstipulate, eplicate. In some words it is intensive merely, in others it has no particular force. Prefixed to names implying office, ex-signifies that the person has held but is now ‘out of’ that office: as, ex-president, ex-minister, ex-senator.
    • ex- An abbreviation of Exodus.

By definition, (Y , eY ) ∈ Z1 (C ) being isomorphic to I (X ) = (X, eX ) (where eX (Z ) = c(X, Z )) means that there is an isomorphism u : X → Y in C such that eY (Z ) = idZ ⊗ u ◦ ex (Z ) ◦ u−1 ⊗ idZ .

Using the definition of I and the definition of the braiding in Z1 (C ) by c((X, eX ), (Y , eY )) = eX (Y ) we obtain Ob j Z1 (C ) ∩ I (C )′ = {(X, eX ) ∈ Z1 (C ) | eX (Y ) ◦ c(Y , X ) = idY X }.
