Replacing some data from a column with another column data only where a certain condition is met in R (dplyr)

I have an extensive data frame with 30+ columns and 10000+ rows. Today I want to focus in two columns: languages and languages2:

languages             languages2

Spanish                  NA
Spanish                  NA
Other (specify)        French
Other (specify)        German
Other (specify)        Russian
English                  NA
Other (specify)        Portuguese
English                  NA
(...)

This is what I need:

languages

Spanish
Spanish
French
German
Russian
English
Portuguese
English
(...)

I am looking for an answer using mutate function from dplyr

>Solution :

data %>% 
  mutate(languages=if_else(languages=="Other (specify)", languages2, languages)
