Ever wonder what the rules were for when to use thou, thee, ye, or you in Shakespeare or the King James Bible?
For example, the inscription on front of the Main Building at The University of Texas says
Ye shall know the truth and the truth shall make you free.
Why ye at the beginning and you at the end?
The latest episode of The History of English Podcast explains what the rules were and how they came to be. Regarding the UT inscription, ye was the subject form of the second person plural and you was the object form. Eventually you became used for subject and object, singular and plural.
The singular subject form was thou and the singular object form was thee. For example, the opening lines of Shakespeare’s Sonnet 18:
Shall I compare thee to a summer’s day?
Thou art more lovely and more temperate.
Originally the singular forms were intimate and the plural forms were formal. Only later did thee and thou take on an air of reverence or formality.
