Word! I knew that the half-sized ‘tsu’ meant a paired consonant, but it never occurred to me to just, you know, … type a pair of consonants.
My favorite learning tool is the LingoDeer app. I think it does a much better job than Duolingo at grammar, at introducing new vocabulary; at everything, really. It also gives you the option of learning with kana alone, or with kana & kanji combined. I just started using Duolingo a couple of weeks ago, and I don’t find it all that impressive. I had Memrise for about a week and decided it was a waste of my phones’ memory. Drops is good for vocabulary, but I haven’t seen anything about sentences yet.
I started with Dr. Moku’s kana, and thought they were fabulous- I literally knew the basic hiragana within 2 days. Learn Japanese by Howard Peebles is very good too.
I’ve been trying to learn kanji on my own for several months. I’ve made more progress this week using the Tsurukame app than I had in all the previous months. Tsurukame seems to be integrated with the WaniKani website, too.
