The `ph’ in the first syllable sounds like the `f’ in `fish’, `feel’ and `full’; the `l..e..g’ that follows sounds like the word `leg’. The following syllable is pronounced like the word `mat’, and the final `ic’ is like the `ic’ in `picnic’ and `fantastic’. The main stress is on the second syllable `mat’; the word sounds like `flegmatic’.
The word is normally used to talk about an individual’s temperament. When you say that someone is phlegmatic, what you mean is that person remains cool under pressure. He remains unemotional.
Example: As expected, the champion remained phlegmatic throughout the tense fifth set.
