Favourite word or word combination.

I seem to relish the chance to use the word that means to humanise something that’s not human - anthropomorphisation.

And I particularly love the specific form - “Anthropomorphic Personification”

I like “Eschew obfuscation”, though it’s lost its irony for me since both have passed into my everyday vocabulary.

Cellar door.

Fell swoop.

Reckless incendiary anecdote. (Thanks, mangetout.)

Mangetout.

Lately it’s pulchritude.

Similar to the OP’s choice: anthropocentrism, which describes the common fallacy of seeing life, the Universe and everything mainly as it relates to humans.

I actually keep a list lol. My love affair with cool words and phrases started in High School when I received the book “Superior Person’s Book of Words”, which contained definitions and sometimes origins for various obscure, interesting, or high fallutin words such as “sequipedalian”. I then proceeded to write a poem for English class almost entirely made up of those and other obscure or academic words which had the very long and confusing title:

“A SESQUIPEDALIAN SCIOLISTIC PARISOLOGY AND CHARIENTISM, ET HOC GENUS OMNE, WRITTEN DURING AN AFFLATUS, FOR MY KINSFOLKS’ NOSOPOETIC MUNDUNGUS”

You can click the link above to experience the fullness of my teenage smart-assery. Other words and phrases that appeal to me (I’m amused by how many spell check isn’t recognizing as I type…), some for the sound of the word, some for the meaning:

My new favourite is “cominbation”.

Before that: euphony, resonance, evocative, sussurance, zaftig.

I got tired of “zaftig” after reading one too many personal ads. There are no fat women looking for love – they’re either zaftig or Rubenesque.

I’m quite fond of “dipthong” and “lugubrious.”

Imminentizing the Eschaton has been a favorite for a while now.

That’s weird. It doesn’t look mispelled, but it is, spectacularly, mispelled.
