A major factor in the strength of English is its ability to adapt to new technological terms. Robotics is a field with a lot of new terminology. As part of my academic studies, I have encountered the term "teleoperation" a lot. Despite understanding the term, I am confused about why this word is not included in numerous dictionaries. For instance, in the Cambridge dictionary, it spills out this result
We have these words with similar spellings or pronunciations: re-operation, teleportation, etc.
For Longman dictionary, it says
Did you mean: teleportation, teleportations, celebration, etc.
For Oxford English dictionary, it mentions
teleoperation, n: The operation of mechanical devices and systems by remote control.
The Oxford dictionary has some technical definitions, but the word doesn't seem to be highlighted as a new word in English.
What is the reason for not adding teleoperation as a new English word?
