This is from Ken Campbell, the UK's greatest populariser of what he called "wol wontok". https://ianlouisharris.com/tag/piotr-baumann/
(It's a Ken Dodd joke, in pidgin. Original on request. :-) )
Tok pisin was my first language, left with the babysitter when growing up.
The more those objects got in daily lives, the more incentives was to find proper words.
The point of my comment was to find an example of a _natural_ language where people came up with ways to refer to new objects by using simple vocabulary (As opposed to a conlang like toki pona)
I want to know how/where the word for plane came from? balus
But also remember the tok pisin is a recent language, created from the colonisation efforts so it's not strange to find that modern words will have a translatation. Helicopters and piano's were around at the time.
The thing with pidgins is that when they start out, they are everybody's foreign language and are used as lingua franca. Generally people have their own native language where they may or may not have words for a given concept but then when they talk with other people from another language group they may or may not be able to just sneak in such a word and be understood. That's why sometimes long turn of phrases are used to describe stuff; not because the speaker doesn't have a word but because the speaker and the listener don't have a common word.
For example in Tok Pisin helicopter is called "mixmaster bilong Jesus Christ" (Jesus Christ's food blender) or piano: bigpela bokis he got whitepela teeth hegot blackpela teeth sappos you hittim him he cry out (big box with white and black keys that cries out when you hit it)
