Excellency (XLNC)
The four letters, XLNC, sound just like the ten-letter word excellency.
The first two sounds (XL) are the name of a spreadsheet program.
If you arrange the letters in modus operandi alphabetically (addeimNooprsu), the letter N is the middle letter. Also, modus operandi is usually written as an abbreviation, MO, which in the alphabet, would have an N in the middle.
The final letter (C) sounds like sea. Do you see?
