How Hard Is Greek?
I really want to learn it. How hard would you say it is? How much practice a day? Thanks.
Just give it a try! The first step is learning to read the alphabet, then everything else will get easier. The Greek course has many helpful explanations on all the lessons, so I took notes on all of these, which helps me understand the lessons better. Greek is hard, but if you have the motivation, I think it will be fine. For me, Greek mythology and history got me interested in learning Greek. One lesson a day and some review is a good start, I think.
I would say that the level of language learning difficulty depends on a couple of things, like
How close your native language to the one you want to learn
how much you practice
The complexity level of the language
Your interest in the language.
(Not just for Greek, for pretty much any language.)
As far as Greek is concerned, as a native Greek, I think that if your native language is English, the difficulty level is medium. It's probably harder to learn than French, Italian, Spanish or German would be, but definitely easier than Vietnamese, Arabic, Hebrew, Japanese or Chinese. ^.^
That all depends how fluent you want to get in it, and how quickly, I guess. Motivation is a big, big factor.
I think Don and Dimitra are completely right in that it's a 'medium difficulty' language. That's how the US State Department classifies it as well (they rank languages by difficulty).
There are some 'easy' bits to Greek. I'd say around 20% of all Greek words are in some way cognate with English (often via Latin and the Romance languages), so that's a massive help. I think Greek also relies on prefixes and suffixes a lot more than English, so once you're familiar with them, that can often help you to roughly figure out the meanings of words you haven't encountered before.
But there are features like case, conjugation, declension, stressing and gendering which are quite alien to modern English. Syntax is also a lot more flexible than in English. So there are some really hard bits too.
To give you my story, I came to Greek about nine months ago essentially monolingual (I really only had a tiny bit of spoken 'taxi driver Arabic') and with no English grammar knowledge whatsoever.
Excluding about two months when I was travelling and couldn't practice, I've been putting in at least 20 hours a week (often more) between Duo/Memrise/Clozemaster and reading Greek children's books etc. I haven't taken any formal lessons yet (will start those soon), but I'd say I've got a vocab in the range of 6,000 words, can put together simple sentences and can just about read most Greek kids' books aimed at 4-6 year olds.
Last time I was in Greece (around four months ago) I had absolutely no problem making all my needs understood in Greek - albeit in pidgin Greek, with completely incorrect grammar and syntax, using basic/somewhat incorrect words. I couldn't understand a word that was said back to me though, and that's probably still what I find hardest about Greek.
Good luck, anyway. I'd highly recommend it and I'm really enjoying it.
