have a past meaning (cf. it is easily broken). Thus pre date (gave) does not mean given. As a postposited epithet pre date could mean having given, which is the correct equivalent of a true active past participle, e.g.:

Un avi, pre kine apo
The bird, having moved away

Passive constructions of Interglossa involve the operator gene (get, become), and the literal equivalent of an English past participle used as an adjective is usually the combination pre gene with an amplifier. Pre date thermo means has heated, having heated, or simply heated as finite verb-equivalent; and pre gene thermo means was heated, has been heated, or simply heated as a postposited adjectival participle equivalent to a relative clause beginning with su (su pre gene thermo = that was heated). To avoid periphrasis and to provide for occasional constructions involving a simple verboid as a passive participle, Interglossa has a passive particle: (472) ge = that has got.

Ge is equivalent to su pre gene. Placed in front of an amplifier, the couplet has the force of a passive participle or equivalent relative clause. Being relatively short, a ge-couplet can take the initial position:

u ge baro gasi = a compressed gas
u ge stereo haema = clotted blood
u ge dicte verba = the spoken word

The first two have the same meaning as:

u gasi, (su) pre gene baro
un haema, (su) pre gene stereo

Comparison of Basic and Interglossa Operators

The range and use of some of the operators of Basic and Interglossa agree closely. Acte, gene, tene, correspond to do, get, keep. The transitive mote is roughly the same as put. The English verb take can mean to carry (acte phoro), but otherwise corresponds closely to tracte. The idiomatic vagaries of give and make as alternative causative operators (cf. give X trouble and make X cold) disappear, because facte means make only when equivalent to construct or manufacture. Similarly, the redundant or meaningless distinction between come and go disappears. Both merge in kine. The inconsistencies due to overlap of the territories of have and be do not crop up, because eque expresses nothing more than identity or class membership in contradistinction to existence
