Answer: Field. A field refers to an open area free of bushes, trees, and buildings. Therefore, the field is the correct answer here.
Even though the field is an area that is comparatively spacious and open, the field has different meanings. For instance, it can be a sports field or an agriculture field.
While the answer “field” can be suitable for “an open area free of woods and buildings”, several other synonyms can also fit. For instance, to refer to “an open area free of woods and buildings”, you can use words like plot, grassland, pasture, enclosure, etc.
If you are wondering what is the dictionary definition of the field, then this is for you-
Field: This is an open land area that is planted with pasture or crops and classically bounded by wooden fences or hedges as well as includes some buildings around it.
Therefore, a field is an open area where you will see some buildings and a large number of woods in it. However, if “field” is an option in your question for “an open area free of woods and buildings”, you should go with this option.
