Simple & complex Words Part 2

What is a morpheme?

• The smallest meaningful part of a word.

• You can't break it down further while keeping meaning.

Examples

• cat → 1 morpheme (can't split it)

• printer → 2 morphemes: print + -er

• unfortunately → 4 morphemes: un- + fortun(e) + -ate + -ly

  Two main types of morphemes

• Free morpheme → can stand alone as a word by itself Examples: cat, print, fortune, rubbish

• Bound morpheme → cannot stand alone; must be attached to something else Examples: un-, -er, -ly, -ate, im-, il-, ir-

Three types of words (based on structure)

Simple

Just one free morpheme

sketch

sketch (that's it)

Compound

Two (or more) free morphemes joined

sketchpad

sketch + pad

Complex

A root + at least one bound morpheme

sketchy

sketch + -y

dispel

dis- + pel

impolite

im- + polite

Roots and bases

• The root is the core part of a word that carries the main meaning.

  Can be free (e.g. origin in "original") or bound (e.g. -pel in "compel/expel/repel").

• A base is whatever you attach new pieces (bound morphemes) to. Example: origin → original → originality → originally (each step adds a bound morpheme to the previous base)

Allomorphs – "shape-shifting" versions of the same morpheme

The same meaning can appear in slightly different forms depending on the sounds around it. Example: the "not/opposite" prefix

• in- (inelegant)

• im- (impolite, immature, imbalance)

• il- (illegal, illegible)

• ir- (irregular, irresponsible)

These aren't four different prefixes — they are allomorphs (different versions) of one abstract morpheme meaning "not". The form changes to make the word easier to say (e.g. im- before p/b/m sounds because they're made with the lips).

Quick takeaway for beginners

Words are like building blocks:

• Some blocks stand alone (free morphemes).

• Some only stick to others (bound morphemes).

• You can combine them to make:

• Simple words (one block)

• Compound words (free + free)

• Complex words (root + bound piece(s))

This is similar to how sentences work (simple, compound, complex) — the same idea of combining smaller meaningful parts!

That's the main stuff explained simply.
