Difficulty: Very hardConsonant Clusters

When analyzing English words strictly by their spoken consonant sounds rather than their orthographic spelling, which of the following words features both an initial consonant cluster of two sounds and a final consonant cluster of three sounds?

  1. craftsAnswer
  2. B
    wrists
  3. C
    sculpts
  4. D
    knights

Answer

The word 'crafts' contains an initial consonant cluster of two sounds (/kr/) and a final consonant cluster of three sounds (/fts/).
The word 'crafts' is phonetically transcribed as /kræfts/ or /krɑːfts/. At the beginning of the word, /k/ and /r/ form an initial cluster of 2 consonant sounds. At the end of the word, /f/, /t/, and /s/ form a final cluster of 3 consonant sounds, perfectly meeting both criteria.

Step-by-Step Solution

1
Transcribe each candidate word into its accurate phonetic representation, identifying and ignoring silent letters.
'crafts' → /kræfts/; 'wrists' → /rɪsts/; 'sculpts' → /skʌlpts/; 'knights' → /naɪts/.
Consonant clusters are defined exclusively by sequences of adjacent consonant sounds in speech, not by written consonant letters.
2
Analyze the onset (initial sound sequence) of each word to find a 2-consonant cluster.
'crafts' has /kr/ (2 sounds); 'sculpts' has /sk/ (2 sounds); 'wrists' starts with /r/ (1 sound, silent 'w'); 'knights' starts with /n/ (1 sound, silent 'k').
Words with silent initial letters do not form initial clusters.
3
Analyze the coda (final sound sequence) of words with valid initial clusters to find a 3-consonant cluster.
'crafts' ends in /fts/ (3 sounds: /f/ + /t/ + /s/); 'sculpts' ends in /lpts/ (4 sounds: /l/ + /p/ + /t/ + /s/).
Matching both constraints requires evaluating both initial and final phonetic positions.
