The word lent is from an Old English word meaning springtime. Among Christians, it probably came to be used as a sort of shorthand for the lenten fast - literally, the great fast prior to Easter which, in the northern hemisphere where the terminology was coined, always takes place during the spring.
There are other fasting seasons throughout the year, of course, but some Orthodox Christians also call these by the name "lent", as though the word is some sort of synonym for fast, which, of course, it isn't. It is not unusual to hear such expressions as Dormition lent, Apostles' lent, and so forth. This makes no sense. They are fasts, not lents.
I would be interested to learn what terminology is used in Russian or Greek, for example, to refer to the fasting seasons. I assume that it is some word for "fast" and not a time of year.
Just saying.
