Answer:
The movie was nearly sold out, but luckily we got tickets.
Step-by-step explanation:
The word that is misspelled is "luckly". The mistake comes from the removal of the final -y from the original adjective "lucky". To transform the adjective "lucky" into the adverb we need for the sentence, we must change the final -y into -i, and then add the suffix -ly. Thus:
lucky --> luckily
Therefore, the correct sentence would be: The movie was nearly sold out, but luckily we got tickets.
