Results. A ratings system was designed in terms of how difficult it would be for an English-language speaker to learn the language. In the case of English, English was judged according to how hard it would be for a non-English speaker to learn the language. Speaking, reading and writing were all considered.
Ratings: Languages are rated 1-6, easiest to hardest. 1 = easiest, 2 = moderately easy to average, 3 = average to moderately difficult, 4 = very difficult, 5 = extremely difficult, 6 = most difficult of all. Ratings are impressionistic.
Time needed. Time needed for an English language speaker to learn the language “reasonably well”: Level 1 languages = 3 months-1 year. Level 2 languages = 6 months-1 year. Level 3 languages = 1-2 years. Level 4 languages = 2 years. Level 5 languages = 3-4 years, but some may take longer. Level 6 languages = more than 4 years.
This post will look at the Tamil language in terms of how difficult it would be for an English speaker to learn it.
Tamil, a Dravidian language is hard, but probably not as difficult as Malayalam is. Tamil has an incredible 247 characters in its alphabet. Nevertheless, most of those are consonant-vowel combinations, so it is almost more of a syllabary than an alphabet. Going by what would traditionally be considered alphabetic symbols, there are probably only 72 real symbols in the alphabet. Nevertheless, Tamil probably has one of the easier Indic scripts as Tamil has fewer characters than other scripts due to its lack of aspiration. Compare to Devanagari’s over 1,000 characters.
But no Indic script is easy. A problem with Tamil is that all of the characters seem to look alike. It is even worse than Devanagari in that regard. However, the more rounded scripts such as Kannada, Sinhala, Telegu and Malayalam have that problem to a worse degree. Tamil has a few sharp corners in the characters that helps to disambiguate them.
In addition, as with other languages, words are written one way and pronounced another. However, there are claims that the difficulty of Tamil’s diglossia is overrated.
Tamil has two different registers for written and spoken speech, but the differences are not large, so this problem is exaggerated. Both Tamil and Malayalam are spoken very fast and have extremely complicated, nearly impenetrable scripts. If Westerners try to speak a Dravidian language in south India, more often than not the Dravidian speaker will simply address them in English rather than try to accommodate them.
Tamil has the odd evidential mood, similar to Bulgarian.
However, on the plus side, the language does seem to be very logical and regular, almost like German in that regard. In addition, there are a lot of language learning materials for Tamil.
Tamil is rated 4, very difficult.
