Podcast 1 — Introduction & meaning

Narrator: Today's word is "Phlegmatic" — adjective, pronounced /flɛɡˈmatɪk/, with the stress on "mat".

Narrator: Someone described as phlegmatic is calm, unemotional and difficult to excite, even under pressure.

Narrator: In plain English, it describes a person who simply does not get worked up about things.

Narrator: It comes from the Greek word phlegma, one of the four humours of ancient medicine, which was thought to make a person sluggish and cool-tempered.

Narrator: A common collocation is a phlegmatic temperament, which describes a steady, unflappable personality.

Narrator: It differs from apathetic, because apathetic suggests a lack of caring, while phlegmatic suggests caring quietly without visible agitation.

Narrator: We also speak of a phlegmatic response, meaning a reaction that is measured and almost disappointingly undramatic.

Narrator: Psychology, literature, sports commentary and business writing all rely on the word when describing composure under strain.

Narrator: So remember: phlegmatic means cool-headed and hard to ruffle, a calmness that comes from temperament rather than effort.

Podcast 2 — In conversation

Speaker A: Why do we call a calm person phlegmatic, of all things?

Speaker B: Wonderful question! PHLEGMATIC comes from the Greek phlegma, one of the four bodily humours, and a person full of it was believed to be cool, slow and serene.

Speaker A: So the medical theory died but the personality type survived?

Speaker B: Exactly so, and it survived beautifully, because we still need a word for the person who stays serene while the office panics.

Speaker A: Example sentences?

Speaker B: "The captain remained phlegmatic as the storm worsened" — he stayed composed. "She gave a phlegmatic shrug at the bad news" — an unbothered reaction. "His phlegmatic manner reassured the whole team" — his calmness steadied others.

Speaker A: Common mistakes?

Speaker B: Do not confuse it with phlegmy or with lazy, because phlegmatic means calm, not sluggish or unwell, and do remember the silent g-h spelling, p-h-l-e-g-m-a-t-i-c.

Speaker A: Close relatives?

Speaker B: Stoical is the serious cousin, unflappable is the everyday twin, and composed is the neat alternative, though phlegmatic keeps its ancient, humoural charm!
