What does it mean when a question is asked what is the base word for technological?
Questions which ask for the "base word" of a word are asking for
etymology, for word history. Many words are made by adding pieces
to the beginnings and ends of other words which change their
meanings slightly. Sometimes the word you started out with gets
lost in the process. So in English we had a word "hap" which meant
good luck or fortune, and someone who was lucky that way was
"happy", and when lucky things occured they "happened", and they
happened "happily". The quality of being happy (which has changed
over the years to mean how you feel when good luck happens to you)
is "happiness" and so on.
So there are two Greek words, techne which means art or craft,
the ability to make things, and logos which means word or
knowledge. From these we get "technology" which means the knowledge
of how to make things. Now technology is a noun, but we might need
an adjective to describe something that has to do with technology.
So we add "-al" onto the end of the word, making it into
"technological". "Technology" is the base word, and "techne" and
"logos" are the root words of "technological".
