📖 1. Word Classes and Morphological Structure

🔑 Key Concepts & Definitions

• Derived word : consists of a stem combined with one or more affixes
• Compound word : A compound word is formed from free morphemes, as in “mother ship”, “mother-in-law”, and “motherboard”.

★ Must-know

📌 Grammatical items are words such as “the” and “at”, whereas lexical items are nouns, verbs, adjectives, and adverbs.

📌 A simple word contains one morpheme, whereas a complex word contains more than one morpheme.

Further detail

📌 Separable prefixes have an autonomous meaning and are neutral in word stress, whereas inseparable prefixes have an integrated meaning within the derivative.

💡 Memory Hook

Grammatical items contrast with lexical items; simple words contrast with complex words.

📖 2. Stress Characteristics and Levels

🔑 Key Concepts & Definitions

• Primary stress : Primary stress is the prominence produced by pitch movement and is marked with ˈ.
• Secondary stress : Secondary stress is prominence without the pitch movement associated with primary stress and is marked with ˌ.

★ Must-know

📌 Stressed syllables are generally louder, longer, higher in pitch, more energetic, and pronounced with full vowels, whereas unstressed syllables are quieter, shorter, lower, weaker, and commonly contain /ə/, /i/, /u/, or /ɪ/.

Further detail

• In “collect”, the stress pattern is /kəˈlekt/, while “comprehensive” has the pattern /ˌkɒmprɪˈhensɪv/.

💡 Memory Hook

Stressed syllables are longer, louder, higher, and fuller; unstressed syllables are shorter, quieter, and reduced.

📖 3. Principles of Stress Placement

★ Must-know

• Every lexical unit has exactly one primary stress.

• A lexical unit must contain a primary or secondary stress on one of its first two syllables.

• Two stresses cannot occur next to each other in a lexical unit, except in compounds.

• No stress can occur after the primary stress in a lexical unit.

Further detail

• “Collect” has the stress pattern 01, whereas “recollection” has the pattern 2010.

💡 Memory Hook

Primary stress first, early stress required, adjacent stresses forbidden, later stress excluded.

📖 4. Stress in Compound Words

★ Must-know

• Compound stress is assigned by first determining the primary stress of each free morpheme, then deciding the number of stresses, and finally assigning their positions.

📌 The general compound rule places one stress on the primary-stressed syllable of the first element.

📌 Two-stress compounds place primary stress on the second element and secondary stress on the first element.

Further detail

📌 In compounds ending in “-ever” or “-self/selves”, stress falls on the ending, whereas compounds beginning with “any-”, “every-”, “no-”, or “some-” generally have stress on the first syllable.

• Two-stress compounds include: compound adjectives, geographical names, compounds specifying the material or nature of the second element, adjective-plus-noun compounds

💡 Memory Hook

Stress the parts first, then count the compound stresses and assign their positions.

📖 5. Neutral Affixes and Stress Reduction

★ Must-know

• Neutral grammatical suffixes include:
  • -(e)s
  • -ing
  • -ed
  • -er
  • -est

• Stress analysis begins by:
  • Identifying the lexical word.
  • Deleting separable prefixes.
  • Deleting neutral suffixes.
  • Applying the remaining stress rules.

Further detail

• In “sleeplessness”, “-less” and “-ness” are neutral, so the stress remains on the first syllable: ˈsleeplessness.

• Main neutral lexical suffixes include -cy, -dom, -ess, -en, -er, -fold, -ful, -hood, -ish, -kin, -less, -let, -like, -ly, -man, -ment, -ness, -ry, -ship, -ty, and -y.

💡 Memory Hook

Deleting neutral affixes → reveals the stem stress pattern.

📖 6. Stress-Imposing Endings

★ Must-know

📌 The ending -osis places primary stress on its first syllable, as in neuˈrosis and ˌmetaˈmorphosis.

• Endings that stress the preceding syllable include:
  • -ic(s)
  • -ety/-ity
  • -efy/-ify
  • -ish in verbs
  • -ible/-igible
  • -sive

📌 The ending -ate is pronounced /eɪt/ in verbs and /ət/ in adjectives.

Further detail

• Endings stressed on their first ending syllable include:
  • -itis
  • -oma
  • -ival
  • -cidal

📌 The ending -ate in words of more than two syllables generally places stress two syllables before the ending, as in ˈcelebrate and alˈternate.

💡 Memory Hook

Some endings attract stress to themselves, before themselves, or two syllables before themselves.

📖 7. Two-Syllable Word Rules

★ Must-know

• In two-syllable words ending in -ate, verbs receive final stress, whereas nouns and adjectives receive initial stress.

• An unprefixed two-syllable word not ending in -ate generally has initial stress.

• A prefixed two-syllable noun generally has initial stress, whereas a prefixed non-noun generally has final stress.

Further detail

• The nouns “proverb” and “accent” have initial stress, whereas the non-nouns “begin”, “superb”, and “advice” have final stress.

💡 Memory Hook

Check -ate, then prefixation, then grammatical category.

📖 8. Long Word Stress Rules

★ Must-know

📌 For words longer than two syllables, stress-imposing endings are applied before rules for words without such endings.

📌 When no stress-imposing ending is present, the last non-neutral ending determines the stress position, while neutral endings do not alter it.

Further detail

📌 In longer non-verbs without a stress-imposing ending, words ending in a single consonant plus a vowel generally have stress on the final syllable, whereas words with heavier preceding structures generally have earlier stress.

📌 For verbs without a stress-imposing ending, verbs in -ise/-ize with opaque derivation have stress on the first syllable, while prefixed verbs generally stress the first syllable of the stem.

• In “conventional”, -al is neutral after -ion, so primary stress falls on the syllable before -ion: conˈventional.

💡 Memory Hook

Check imposing endings first; otherwise apply the final non-neutral ending and word-pattern rules.
