Preposition for Suffering

Choosing the correct preposition is essential for clear and accurate communication in English. Prepositions connect nouns, pronouns, or phrases to other words in a sentence, indicating relationships such as time, place, direction, or cause. In the given sentence, we need to select the appropriate preposition to complete the phrase "I am suffering ______ depression."

Understanding "Suffering From"

The verb "to suffer" is commonly used with the preposition "from" when referring to experiencing a disease, illness, pain, or any unpleasant condition. This phrasal verb, "suffer from," specifically indicates that someone is afflicted by or enduring a particular ailment or problem.

• When a person is experiencing a health issue or a chronic condition, "from" is the standard preposition used with "suffer."
• Examples include: suffering from a cold, suffering from back pain, suffering from anxiety, or suffering from depression.

Analyzing the Options

Let's examine each option to determine its suitability in the context of "I am suffering ______ depression."

• "of": The preposition "of" is generally used to indicate possession, origin, or a part of something (e.g., "the causes of depression," "a member of the team"). It is not used with "suffer" to denote an illness. Therefore, "I am suffering of depression" is grammatically incorrect.
• "by": The preposition "by" is often used to indicate the agent, means, or proximity (e.g., "written by hand," "standing by the door"). While one might be affected by something, "suffering by" is not the correct idiomatic expression for enduring an illness. Thus, "I am suffering by depression" is incorrect.
• "at": The preposition "at" typically indicates a specific location, time, or state (e.g., "at home," "at noon," "at peace"). It does not fit the context of experiencing an illness. Therefore, "I am suffering at depression" is grammatically incorrect.
• "from": As discussed, "from" is the correct and idiomatic preposition to use with "suffer" when referring to an illness or condition. It clearly conveys that the person is experiencing or afflicted by depression. Hence, "I am suffering from depression" is the grammatically correct and natural-sounding sentence.

Correct Sentence Construction

Based on the analysis, the correct preposition to complete the sentence is "from."

The complete and grammatically correct sentence is:

I am suffering from depression.
