Deletion of Porul ilakkanam

Comment: This is a tough one, but I'm saying keep. There is some coverage discussed above and cited in the article that's marginal at best in terms of its |reliability, but I don't think anyone disputes that this is one of the five parts of Tamil grammar; I, at least, don't doubt that that's the case. Naturally, this will be covered extensively in Tamil grammar books, which will almost uniformly have to be in Tamil. Thus it shouldn't come as a surprise that there are  issues with English sourcing or that sourcing is difficult to find. Moreover, as a fundamental concept in Tamil grammar, this is the equivalent in terms of significance to noun, verb or independent clause or predicate (grammar)|predicate, and if we're not ed, it ought to be included. This argument may be critiqued as , but I think this is one rare case where an  argument carries water
Stance: keep
