The term 'more spacious' can be described by four different words, all of which have seven or six letters. The first word is 'roomier', which means having more space or room. The second word is 'ampler', which means having a greater amount or size. The third word is 'LARGER', which means having a greater size or capacity. Finally, the fourth word is 'vaster', which means having an even greater size or area. All of these words describe the concept of having more space or room than what was previously available.
