How long to to learn Polish? In hours? [64]
Ah, and there's the rub! To communicate on a BASIC level need not necessarily equate to communicating on a culturally, idiomatically NATURAL or fluent level:-)
For the latter, more hours would well be needed than there are in a day (..perhaps, an average lifetime)LOL
Realistically, your estimate might work at a tourist or visitor level, but not too much more. Depends on your expectations! Getting a room at a hotel, maybe even engaging in "light" conversation over a beer, going sightseeing etc. is a far different kettle of fish from being able to attend one of the better Polish universities, hear a target-language lecture on Mickiewicz, enjoy a Polish classic film without subtitles etc.. and be able to discuss it cogently IN POLISH among educated native speakers at a high class cocktail party!
Far too often, we all tend to confuse ease in communication with natural fluency, pleasing to a native speaker of the language we're studying. Many Poles have to be sure studied English at university many years, have gone on study trips to the States or the UK and believe themselves to be totally aka far exceeding merely "adequate" in English.
Except for only one person I've known for years, the others failed, many miserably, arrogantly insisting that "minor mistakes" are unimportant.....
If a Pole were to ask me for an honest assessment of my Polish skills, I'd respond that I'm an advanced "beginner" in the language, yet am always open to learn more, and I'd be right.
