how to "reverse" the output bash

Question

I have an output that looks like this: (number of occurrences of the word, and the word)

    3 I
    2 come
    2 from
    1 Slovenia

But I want that it looked like this:

I 3
come 2
from 2
Slovenia 1

I got my output with:

cut -d' ' -f1 "file" | uniq -c | sort -nr

I tried to do different things, with another pipes:

 cut -d' ' -f1 "file" | uniq -c | sort -nr | cut -d' ' -f8 ...?

which is a good start, because I have the words on the first place..buuut I have no access to the number of occurrences?

AWK and SED are not allowed!

EDIT: alright lets say the file looks like this.

I ....
come ...
from ... 
Slovenia ...
I ...
I ....
come ...
from ....

I is repeated 3 times, come twice, from twice, Slovenia once. +They are on beginning of each line.

AWK and SED are not allowed!

Starting with this:

$ cat file
    3 I
    2 come
    2 from
    1 Slovenia

The order can be reversed with this:

$ while read count word; do echo "$word $count"; done <file
I 3
come 2
from 2
Slovenia 1

Complete pipeline

Let us start with:

$ cat file2
I ....
come ...
from ... 
Slovenia ...
I ...
I ....
come ...
from ....

Using your pipeline (with two changes) combined with the while loop:

$ cut -d' ' -f1 "file2" | sort | uniq -c | sort -snr | while read count word; do echo "$word $count"; done 
I 3
come 2
from 2
Slovenia 1

The one change that I made to the pipeline was to put a sort before uniq -c. This is because uniq -c assumes that its input is sorted. The second change is to add the -s option to the second sort so that the alphabetical order of the words with the same count is not lost
