From the geology course I took in 1975: Minerals are naturally occurring crystals of compound. Snow is a mineral, but volcanic glass is not. Rocks are amalgams of minerals and non-minerals.
In corpus linguistics, a collocation is a sequence of words or terms that co-occur more often than would be expected by chance. In phraseology, collocation is a sub-type of phraseme. An example of a phraseological collocation, as propounded by Michael Halliday, is the expression strong tea.
A saying that expresses something other than the literal meaning of the words it contains is a colloquialism, like saying I wasn't born yesterday, to mean you can't fool me.. Colloquialism comes from the Latin word colloquium meaning conference, conversation, or literally a speaking together.. When you talk, colloquialisms are so common, you might not be aware you are using them â that is, until one comes up that is unfamiliar to someone in the group.
