The problem involves a simple substitution cipher where words are represented by specific codes. We are given two coded phrases and need to find the code for the word 'birds'.
By comparing the common word 'birds' with the common code 'ly' across the two provided examples, we can deduce the correct coding.
The code for 'birds' is 'ly'.
In a certain code language, 'let me speak' is coded as 'ko df ty' and 'speak the truth' is coded as 'df op np'. How is 'speak' coded in the given language?
(All codes are two-letter codes)
