15. Some types of symmetrical tanru

This section deals with symmetrical tanru, where order is not important. Many of these tanru can be expressed with a logical or non-logical connective between the components.

The tanru may refer to things which are correctly specified by both tanru components. Some of these instances may also be seen as asymmetrical tanru where the seltau specifies a material. The connective “je” is appropriate:

cipnrstrigi pacru'i
owl demon (Skt) nolraitru prije royal sage (Skt) remna nakni human-being male (Qab ⇔ man) remna fetsi human-being female (Qab ⇔ woman) sonci tolvri soldier coward (Que) panzi nanmu offspring man (Ewe ⇔ son) panzi ninmu offspring woman (Ewe ⇔ daughter) solji sicni gold coin (Tur) solji junla gold watch (Tur,Kor,Hun) solji djine gold ring (Udm,Aba,Que) rokci zdani stone house (Imb) mudri zdani wooden house (Ewe) rokci bitmu stone wall (Ewe) solji carce gold chariot (Skt) mudri xarci wooden weapon (Skt) zdani tcadu home town (Chi) cipnrstrigi ⇔ fu'ivla for “owl” based on Linnean name pacru'i ⇔ evil-spirit tolvri ⇔ opposite-of-brave
The tanru may refer to all things which are specified by either of the tanru components. The connective “ja” is appropriate:
nunji'a nunterji'a
victory defeat (Skt ⇔ victory or defeat) donri nicte day night (Skt ⇔ day and night) lunra tarci moon stars (Skt = moon and stars) patfu mamta father mother (Imb,Kaz,Chi = parents) tuple birka leg arm (Kaz ⇔ extremity) nuncti nunpinxe eating drinking (Udm ⇔ cuisine) bersa tixnu son daughter (Chi ⇔ children) nunji'a ⇔ event-of-winning nunterji'a ⇔ event-of-losing nuncti ⇔ event-of-eating nunpinxe ⇔ event-of-drinking
Alternatively, the tanru may refer to things which are specified by either of the tanru components or by some more inclusive class of things which the components typify:
curnu jalra
worm beetle (Mon ⇔ insect) jalra curnu beetle worm (Mon = insect) kabri palta cup plate (Kaz ⇔ crockery) jipci gunse hen goose (Qab ⇔ housefowl) xrula tricu flower tree (Chi = vegetation)
The tanru components specify crucial or typical parts of the referent of the tanru as a whole:
tumla vacri
land air (Fin ⇔ world) moklu stedu mouth head (Aba = face) sudysrasu cunmi hay millet (Qab ⇔ agriculture) gugde ciste state system (Mon ⇔ politics) prenu so'imei people multitude (Mon ⇔ masses) djacu dertu water earth (Chi = climate) sudysrasu ⇔ dry-grass so'imei ⇔ manysome
