In its grammatical structure, English belongs to the Low German language family, a group of languages that developed from a common early Germanic root. The group includes Flemish, Dutch, Frisian, Afrikaans (the Dutch that is spoken in South Africa), Plautdietsch, English and Scots (not Gaelic but the variety of old English spoken by the lowland Scots, such as the poet Robbie Burns).
However, something like 40% of English words come from French. Oftentimes meanings, spelling and pronunciation have shifted to the point that the French roots are almost invisible. Take geezer for instance. This is a word that was originally applied to someone who went about in a disguise, or more simply, in the guise of someone different from himself. Since guise is a word of French origin it was originally pronounced geez. Over a few hundred years the meaning of geezer shifted to where it is now used only for an older person who has become a little different in appearance and mannerisms.
In many other words the French roots are plainly visible, though often not understood by English speakers. Take grammar for instance, which is what I want to talk about in this article.

All English grammatical terms are French, beginning with grammar itself. Grammar comes from grammaire in French, which comes from a Greek word meaning the art of reading and writing. A noun is the name of a thing, chair for instance, and comes from the French word nom, meaning name. Most other grammatical terms are spelled the same, or almost the same, in English as in French: verbe, adverbe, adjectif or adjective, préposition, article, objet direct or indirect, conjonction, etc.
It may be helpful for English speakers to understand the roots of terms like tense and mood. Both are mispronunciations of French words, which led to misspellings, making them homonyms of English words with completely different meanings.
Tense comes from temps, which means time. Past, present and future should be called times, not tenses. Obvious, eh? But the French pronunciation of temps is something that is beyond the capacity of the vocal apparatus of someone who grew up speaking English, so it drifted over to become tense.
There are three basic past tenses: simple past, imperfect and pluperfect. Perfect is another word of French origin that we often misunderstand. It simply means finished or complete, or, in the case of people, grown up or mature. Neither in grammar nor in the Bible does it ever mean faultless. Imperfect means incomplete and refers to an action that began in the past and is not complete. Pluperfect (plus-que-parfait in French) means more than complete and refers to an action that was complete in the past before something else happened.
For instance: I had gone (pluperfect) into Tim Horton’s and was ordering (imperfect) a coffee when my cousin walked (simple past) in.
Mood comes from the French word mode and should be mode in English also. Once again, a native English speaker cannot really duplicate the sound of mode in French. Nevertheless, the grammatical term mood in English refers to a mode of expressing one’s meaning.
The indicative mood (mode) is used for an action that has actually happened, is happening, or that we know will happen. The conditional mood (mode) is used for actions that could, should or would happen if some other condition is met, had been met or will be met.
Examples: The plane will be landing in fifteen minutes (indicative).
The plane should be landing in fifteen minutes if it left Toronto on time (conditional).
And then there’s the subjunctive mood, but that is going to require a whole article of its own.
