In speech, words link together as a continuous flow of syllables just as they do within a word. There is no break between spoken words as there is with written words. When one word ends in a consonant sound, and the following word begins with a vowel sound, the ending consonant sound of the first word sounds like the beginning of the second word. "Turn over" sounds like "tur nover". To "turn over a new leaf" means to change for the better or to make a new start.
