In letter-letter coding, the candidate will have to get words from letters. Getting words from letters that we arrange as per a certain pattern or code is the topic of this section on Letter-letter coding. In general, we say that Getting words from letters is set up to judge the candidate’s ability to decipher the rule that codes a particular word/message and break the code.
Words From Letters
A code is a ‘system of signals’. Therefore, Coding is a method of transmitting a message between the sender and the receiver without a third person knowing it. In these questions, the real alphabets in a word are replaced by certain other alphabets according to a specific rule to form its code. The candidate is required to detect the common rule and answer the questions accordingly.

In the following section, we will focus on the concept and method of obtaining words from letters and letters from words.
Example 1: If in a certain language MYSTIFY is coded as NZTUJGZ, how is NEMESIS coded in that language?
(a) M D L H R D R (b) O F N F T J T (c) O D N H T D R (d) P G O K U G U
Solution: Clearly, each letter in the word MYSTIFY is moved one step forward to obtain
the corresponding letter of the code.
M – Y S T I F Y
N – Z T U J G Z
So, in N E M E S I S, N will be coded as O, E as F, M as N and so on. Thus, the code becomes O F N F T J T. Hence, the answer is (b) O F N F T J T.
Example 2: If T A P is coded as S Z O. then how is F R E E Z E coded?
(a) E Q D F Y G (b) E S D F Y F (c) G Q F D Y F (d) V J E Q D D Y D
Solution: Clearly, each letter in the word T A P is moved one step backwards to obtain
the corresponding letter of the code. Thus, in F R E E Z E, F will be coded as E, R as Q, E as D and Z as Y. So, the code becomes E Q D D Y D. Hence, the answer is (d) V J E Q D D Y D.
Example 3: In a certain code, SIKKIM is written as THLJJL. How is TRAINING written in that code? (BSRB 1997)
(a) SQBHOHOH (b) UQBHOHOF
(c) UQBJOHHO (d) UQBJOHOH (e) None of these
Solution: Clearly, the letters in the word SIKKIM are moved alternately one step forward and one step backwards to obtain the letters of the code.
So, in TRAINING, T will be coded as, U, R as Q, A as B, I as H, N as O and so on. Thus, the code becomes UQBHOHOF. Hence, the answer is (b)
Example 4: In a certain code, MENTION is written as LNEITNO. How is PATTERN written in that code? (BSRB. 1998)
(a) APTTREM (b) PTAETNR (c) OTAETNR (d) OTAETRN (e) None of these
Solution: Clearly, to obtain the code, the first letter of the word MENTION is moved one step backwards and the remaining letters are reversed in order, taking two at a time. So, in PATTERN, P will be coded as 0 and the sequence of the remaining letters in the code would be TAETNR. Thus, the code becomes OTAETNR. Hence, the answer is (c).
Example 5: In a certain code, FORGE is written as FPTJI. How is CULPRIT written in that code? (UJ).C. 1996)
(a) CSJNPGR (b) CVMQSTU (c) CVNSVNZ (d) CXOSULW
Solution: Clearly, the first letter in the word FORGE remains as it is and the second, third, fourth and fifth letters are respectively moved one, two, three and four steps forward to obtain the corresponding letters of the code.
Applying the same rule to the letters of the word CULPRIT, C will( remain unchanged, U will be coded as V, L as N, P as S, R as V, I as N and T as Z. Thus, the code becomes CVNSVNZ.
Hence, the answer is (c).
Q1: If in a code, A L T E R E D is written as Z O G V I V W, then in the same code, R E L A T E D would be written as
(a) I V O Z G V W (b) L V O Z G W V (c) I V O G Z V W (d) V I O Z G V W
Ans: (a) I V O Z G V W
