IntermediateWord Formation
How new words are created through affixation, compounding, and conversion in Spanish, English and Chinese.
Compare languages
English uses prefixes, suffixes, and compounding extensively. Spanish uses affixation and derivation but less compounding. Chinese relies overwhelmingly on compounding and very limited affixation.
Overview
Word formation is how new words are created from existing ones.
- Spanish: Uses derivational affixes extensively (-idad, -mente, -ción, -ero, -dor). Compounding is less common and often less transparent than in English or Chinese.
- English: Uses prefixes, suffixes, compounding, and conversion (zero-derivation) with great productivity. New compounds and conversions appear constantly.
- Chinese: Relies almost entirely on compounding. Affixation is extremely limited. Most words are two-character compounds where each character contributes meaning.

- overcoat, underground, afterthought
Conversion (zero-derivation)
English freely converts words between categories:
| Noun → Verb | Verb → Noun | Adjective → Verb |
|---|---|---|
| email (to email) | run (a run) | empty (to empty) |
| bottle (to bottle) | walk (a walk) | clean (to clean) |

Blending
- smoke + fog = smog
- breakfast + lunch = brunch
- web + log = blog
- emotion + icon = emoji (from Japanese)
Acronyms
- NASA, UNESCO, laser, radar, scuba
Back-formation
- editor → edit (originally editor from Latin, later back-formed edit)
- television → televise
- babysitter → babysit
Chinese
Compounding (primary strategy)
Chinese forms almost all new words by compounding characters:
Modifier + Head:
- 黑板 (black + board = blackboard)
- 火车 (fire + car = train)

- 洗手间 (wash + hand + room = restroom)
Verb + Object:

- 睡觉 (sleep + sleep = sleep)
Verb + Complement:
- 打破 (hit + break = break)
- 看见 (look + see = see)
- 听懂 (listen + understand = understand by listening)
Coordinate:
- 朋友 (friend + friend = friend)
- 学习 (study + practice = study)

English speakers learning Spanish: Casa-coche for garage → garaje (Spanish doesn’t compound freely like English)
-
English speakers learning Chinese: 快乐-ness → 快乐感 (感 adds abstract quality; -ness doesn’t translate directly)
-
Chinese speakers learning English: I am very happiness → I am very happy (English uses adjective, not noun)
-
Spanish speakers learning English: I am agree → I agree (English conversion: adjective → verb, not Spanish agreement verb structure)
