Printing a concatenated string with 'n' adjacent partners

myList = ["This", "is", "a",  "great", "list"]
n = 2
tempN = n

res = []

for i in range(len(myList)-n+1):
    start, tempRes = myList[i], ""

    for j in range(i, len(myList)):
        if tempN>0:
            if tempN == 1:
                tempRes += f"{myList[j]}"
            else:
                tempRes += f"{myList[j]} "

            tempN -= 1
    else:
        res.append(tempRes)
        tempN = n

print(res)

##Output : ['This is', 'is a', 'a great', 'great list']
