Singlish is not a dialect but the semi-demi-literate Singaporean's version of English.
You think of Singlish as a literal translation of an expression in Chinese (or Malay) into English - but without any regard for tenses and sometimes the definite or indefinite article are omitted. And a word is added here and there which while totally meaningless to English speaker nevertheless does convey more to the Singlishman.
For example,
"Do you want ....?"
would be
"You want don't want ...?"
pronounced "You wan don wan"
with the final consonants silent.
"I don't have enough money" OR "There is not enough money" is rendered as "Money no enough" in Singlish.
Sometimes a word found in a Singlish expression can be left out without any loss in meaning, but which the Singlishman still uses anyway.
For example:
English speaker to Singlish air hostess: "So, what were you doing before you became an air hostess?"
Singlish air hostess: "Study law."
(This "law" here can be omitted and not change the meaning. It is used anyway so that the sentence sound more complete, smoother, less abrupt.
English Speaker, thinking that the air hostess used to be a law student: "Why did you give up (law) to be an air hostess? "
Singlish air hostess: "Cannot meh?" meaning "Can I not do it --- give up my studies to be an air hostess." The "meh" here serves the same function as the "law" above.
And of course there is this biquitous
"lah." "Lah" is like "man" to a Brit or like "like" to the Yank.
So the Brit will say, "I'm not hungry man..." while the Singlishman will say "I'm not hungry lah..." Or maybe the yank will say, "I'm like not hungry."
But the difference between English and Singlish is not only in the spelling or pronunciation of individual words or the "fillers" like "man, lah, law". The speech rhythm and speech music are also totally different. Sometimes you do not know whether a man is referring to cemen(t) or semen.
And if you make a phone call, you may hear a recorded message that asks you to "ho on" because no one is free to attend to you.
