Latin is a highly synthetic language, using many suffixes to indicate concerns such as number, gender, formality, possession and tense. Adding these endings is called conjugating for verbs and declining for nouns and adjectives.
I have 2 remarks on this:
1. The last sentence is right as such but it applies to grammar in general, so why should it be mentioned in particular here? Just because the terms "declension" and "conjugation" are derived from Latin?
2. Isn't is better to replace "concerns" with "grammatical categories" here? That seems to be the most proper term. See for example  or Wikipedia: . Stefan Olejniczak 11:58, 13 November 2010 (UTC)
- The last sentence is not really relevant, but could be made to be with examples, I suppose. (2): yes, except for 'formality'. John Stephenson 12:31, 13 November 2010 (UTC)
