As I’ve already mentioned, adjectives in Tagalog are usually formed by putting the affix ma- before the root word. For example, in order to form the adjective beautiful starting from the root word ganda, you need to combine ma with ganda and, therefore, form the adjective maganda.
Not all adjectives, however, are formed that way: sometimes there are adjectives that don’t require any affix, such as: payat (slim), bobo (stupid) and so on.
If you want to say that something is more, let’s say, beautiful than something else, you need to use the following structure: mas maganda kaysa (example: ang Pilipinas ay mas maganda kaysa sa Italya=the Philippines is more beautiful than Italy).
If you want to say that something is the most, let’s say, beautiful among a group you use the affix pinaka- instead of ma- before the root word (example: ang Pilipinas ay ang pinakamagandang bansa sa mundo=the Philippines is the most beautiful country in the world).
If you want to say that something is very beautiful you can use the napaka- affix instead of ma- (example: ang Pilipinas ay napakaganda).
Hope this helps….
