x1 is a zi'evla-shaped compound meaning x2 with arguments x3 built from phrase/tanru x4.
Refers to words are formed the same way as a lujvo by combining words or their affixes but have forms classed as fu'ivla/zi'evla due to different ways of combining. These words often have a fu'ivla/zi'evla at the end (eg. CCV-CVV-CVCCVCV, CV'V-r-CCVCVCV, CVC-CV'VCCV), but may also contain of gismu forms in full combined (e.g. CCVCV-CVCCV) or cmavo without their own rafsi or contain epenthetic consonants besides -r- or -n-, but never the epenthetic vowel -y-. Existing examples include jugmantodi, cmaraimutsteila, frikoxazdo, ko'elmoi, ra'oijbo. See also lujvo, fu'ivla, zi'evla.
