Putting brackets around a specific column-CodePudding

With a bash script, I extracted a .conllu file into a three columned .txt with the Lemma, POS and meaning. So some kind of dictionary. Now I am trying to make it prettier by putting the second column (POS) in brackets.

It looks like:

ami NOUN    mother
amo VERB    sleep
asima   NOUN    younger_sister
ati NOUN    older_sister

Every column is seperated by a tab.

I want it to look like this:

ami (NOUN)  mother
amo (VERB)  sleep
asima   (NOUN)  younger_sister
ati (NOUN)  older_sister

and ideally:

ami (NOUN)  - mother
amo (VERB)  - sleep
asima   (NOUN)  - younger_sister
ati (NOUN)  - older_sister

I tried regex and sed

sed -e 's/[a-zA-Z]  /(/g' -e 's [a-zA-Z] =[a-zA-Z] /)/g' dictjaa.txt > test.txt

but failed unfortunately.

Using sed

sed -E 's/([^[:alpha:]] )([^ ]*)  /\1(\2) -/' input_file
ami (NOUN) -  mother
amo (VERB) -  sleep
asima   (NOUN) -  younger_sister
ati (NOUN) -  older_sister
