Why Do People Write “Absorbsion”?
The confusion comes from the verb absorb.

However, English changes the spelling when forming the noun.
The correct transformation is:
- absorb

- absorption
The b joins directly with tion, producing absorption, not absorbsion.
Understanding the Word Formation
Let’s break it down.
| Base Word | Part of Speech |
|---|---|
| absorb | Verb |
| absorption | Noun |
Notice:
The spelling changes slightly during word formation.
This is common in English.
Similar examples include:
| Verb | Noun |
|---|---|
| describe | description |
| prescribe | prescription |
| subscribe | subscription |
| absorb | absorption |
The spelling follows historical English word development rather than simple letter addition.
Pronunciation
Absorption
IPA (American English):
/əbˈzɔrpʃən/
It sounds like:
ab-ZORP-shun
Notice there is no “bs” sound in the middle.
That is another reason people become confused when spelling it.
Why English Uses “Absorption”
The noun comes from Latin.
Word history:
Latin:
absorbere
↓
Middle French
↓
English absorb
↓
English absorption
The spelling developed through centuries of language evolution rather than modern spelling rules.
