Nice lessons on here, keep going.
One little correction, though: it is 'hasha.' When a syllable letter 'sh' [particularly when it is 'sha'] is added at the end of a word, thus if the last letter on that said word is 'l,' it is omitted, thus in this case the letter 'l' of hal becoming hasha.
Other examples are meel and ul. If meel becomes "the" meel, it thus changed to meeshaan.
Ul becomes usha.
There are other letters that involve this advanced grammatical system, but can't recall now.
