In the corner were corralled a few old desks.
Is it fine to put "were" in front? And why? please give more examples to me. Thank you!
In day-to-day English, this sentence would usually follow the pattern of subject–verb–object (SVO) to become
A few old desks were corralled in the corner.
However, your sentence (which is perfectly valid by the way) is an example of inversion, where the verb is placed before the subject.
Inversion is something we use every day when creating questions (are you hungry?), but in written English, it is a literary technique used for emphasis or special effect, and it makes a sentence sound striking or unusual.
In written English, as well as in a very formal style, inversion can be used in the following cases :
After negative adverbial expressions:
After adverbial expressions of place:
After 'seldom', 'rarely', 'never', and 'little':
After 'hardly', 'scarcely', 'no sooner', when one thing happens after another.
After adverbial expressions beginning with 'only' and 'not only':
After exclamations with 'here' and 'there':
