Despite alleged monstrosities like Finnish lentokonesuihkuturbiinimoottoriapumekaanikkoaliupseerioppilas and German Schützengrabenvernichtungsautomobil, compounds are often shorthand renderings of even longer constructions in Romániço, like capil-brucio (“hairbrush”) from capilisca brucio or brucio por capilos.
Compound words generally consist of a head (a word that expresses the basic meaning of the whole compound) and one or more modifiers. (E.g., handbrake consists of the head brake, the basic meaning of the compound, and hand, describing the sort of brake it is.) The head and modifiers can be separated with a hyphen for the sake of clarity, according to preference.
In English, the head usually comes last in a compound, but this varies from language to language — and often within the same language (e.g., English lockpick and pickpocket, Spanish chupacabra and fazferir). Romániço uses the model of Greek and Latin derived international compounds, where the main element, if any, comes last (e.g., astronaut “star-sailor”, anthropophage “man-eater”).
|acri-dulço||[acra et dulça]-o||bittersweet thing|
|ennigrilistifer||[en nigra listo]-ifer||to blacklist|
|Dicin álicu “Tónitri-furio, benedictita lamno di la venti-cercanto”?||[furio di tónitro, cercanto je vento]||Did someone say “Thunderfury, Blessed Blade of the Windseeker”?|
There are some compounds that denote something other than a form of the head. For example, silverback denotes not a type of back, but a male ape characterized by a silver back, and before-tax denotes not a type of tax, but profits reckoned before taxes. Here, too, Romániço follows the model of Greek and Latin international compounds (e.g., apathy “without-feeling”).
|gris-capilo*||[(álico habanta) grisa capilos]||grayhaired person|
|superhómino||[(álico) super il hómino]||superman|
|abante-cambro||[(álico) abante la cambro]||ante-chamber|
Note that Romániço uses -i- as a connecting vowel between the elements of a compound word. The connecting vowel can be elided, euphony permitting, except when the preceding element ends in unstressed -i-:
|cantist-auctorisca||[cantisto et auctoro]-isca||pertaining to singer-songwriters|
|triángulos||álicos cum [tria ángulos]||triangles|
|cabalarií-practicanto||[practicanto je cabalariío]||chivalry practitioner|
|cacii-coligisto||[cacier et coliger]-isto||hunter-gatherer|
|me-parte||[mea parto]-e||for my part|
|omni-die||[omna dio]-e||every day, as an everyday occurrence|
When a preposition is combined with a verb that can take an object, the preposition is treated as an adverb with an elided -e and the object of the compound is the object of the original verb:
|deprender on capelo||[de-e prender on capelo]||to take off a hat|
When a preposition is combined with a verb of motion that does not take an object, the object of the preposition can be used as the object of the compound to signify motion toward that object:
|advener on concordo||[vener ad on concordo]||to come to an agreement|
|envader on cambro||[vader aden on cambro]||to enter a room|
