The etymology of the word 'bachelor' (1927) was that it referred to as 'a young knight, not old enough, or having too few vassals, to display his own banner, and who therefore followed the banner of another; a novice in arms.' The spelling was also different as to how we spell it nowadays, with the word being spelt 'bacheler'. This shows that this word may have changed with regards to pronunciation and spelling. Another meaning (1936) was that the word bachelor was  'One who has taken the first or lowest degree at a university, who is not yet a master of the Arts' this was often spelt as 'batchelers'. In more recent terms, the word 'bachelor' has come to mean an unmarried man who is at a marriageable age. These days, people would recognize the world bachelor to being a unmarried man who is attractive to females - they tend to have a bachelors pad which is where females are invited round.
