Also called plains are all those whose accent falls on the penultimate syllalaba. So are most of the words in our language. Thus, for example, if we observe the words expressed up to this sentence, we have 12 flat words versus 10 acute (of which 7 are monosyllables) and 2 sydrúlous. They wear all the bass words not finished in -n , -s or vocal. Those that end in -s preceded by another consonant are accentuated and also those finished in - and when it acts as a consonant. E.g. biceps and poney.
