I have learned and speak a number of languages. Some I have learned principally in school, others, the ones I know best, by living in different countries.
But recently I have come to the conclusion I speak and especially write them all badly. Even my mother language, a Scandinavian language. The reason? I have forgotten much grammar. That is embarrassing. Also I tend to mix languages. I must have reached the limit of number of languages or I am getting too old. It can't be the latter so it must be the former.
My language problems especially come to light, when writing texts like the ones in this blog. I still remember there are rules and I also remember to apply some of them. But not all.
Like when to use who or whom. I once learned some rules (sentence object, substitution with his/him, her/she) for that one. The last rule, when in doubt and the other rules don't apply - use who. At least I think that was it. Or is it whom?
I can still analyze a sentence and have no problems with tenses I think. And yet. English is seemingly a very simple language grammatically speaking. But just on the surface. There are so many rules and exceptions. Mostly now, I just play it by ear - the result is predictable.
Hmmh. I have completely forgotten punctuation rules in English. It is no excuse I found the rules illogical, similar to where to divide words in English when spelling.
I promise my reader (I only think I have one so far) and myself, that I will brush up on my English grammar.
BTW a bit out of context: Goethe once said: To know your own language you need to learn another. He was a smart man.
Conclusion: To keep up language skills you need to practice, unless you have a memory beyond mine. That is not unthinkable by the way.
