Language Structure Problems

Changing Consonants

In the problems that follow, you will make a series of changes to a word's consonants and end up, at the other end of the series, with a new word. Sometimes, the intermediate steps will be real English words, and sometimes they will not be. However, every time you alter the voicing, manner or place of articulation of a segment, make sure the resulting segment occurs in standard English even if the entire word which contains it does not. For example, if you are asked to move a bilabial nasal one place of articulation toward the back of the mouth without changing its manner or voicing, the result will be an alveolar nasal [n] since there are no English nasal consonant sounds at the labio-dental or interdental place of articulation.

To answer the questions, simply give the word at the end of the chain. give your word in correct orthography: not transcription.

If you would like to show the intermediate steps, you may, but this is not required.

Sometimes the starting word will be given in orthography and sometimes in transcription. Remember that transcribed words always occur in brackets.
