If I'm going to use the word "Wednesday" in a sentence, and I'm coming up to the word, and I can feel that I'm going to stutter or something, I can change the word to "tomorrow," or "the day after Tuesday," or something else.
Ako ću koristiti  riječ "srijeda" u rečenici, i dolazim do te riječi, i osjećam da ću zamucati ili nešto, mogu promijeniti tu riječ u "sutra," ili "dan poslije utorka," ili nešto drugo.
