Or any other animal ?...We are all born with the skill of language, so communicating as we know is innate ..so just use it !
Easier said that done you may say! Did you know that each person has a way of absorbing a language differently from others?. Some prefer listening to and hearing new words. Some need to see a word written down, and others associate new words with abstract ideas (or other words they already know). So we need to find out which is our own forte.
A good way to absorbing a language is to maybe keep the TV switched on as background sound while we are occupied on other activities. That's the way children have learnt upto five languages at the same time. The brain can distinguish the sounds of each language whatever age group we are in. Each language uses vocal cords and muscles in a different way. Have a go...put the Spanish TV on for a while everyday and let it chatter away.
