Unlock Disciplinary Language

Complex words often contain several meaningful parts. Consolidated morphological knowledge makes unfamiliar academic vocabulary more readable and spellable.

The big idea

Word structure carries a trail of meaning

In decentralization, de- signals reversal, centr is the base, -al forms an adjective, -ize forms a verb, and -ation forms a noun. Context confirms the precise meaning.

Work it through

Analyze the word interdisciplinary

  1. 1. Identify inter- as between or among.
  2. 2. Identify discipline as the base referring to a field of study.
  3. 3. Recognize -ary as forming an adjective.
  4. 4. Test 'involving multiple fields of study' in the sentence, then reread for fluent phrasing.
