Expressing Unreal Sensory Comparisons

When describing sensory perceptions (looks, sounds, feels, etc.) that suggest an unreal situation, we use 'as if/as though' with the past subjunctive. This creates a hypothetical comparison between what we perceive and what seems to be happening.

Sensory Verbs with As If/As Though

Common sensory verbs used with this structure include: looks, sounds, feels, seems, appears, tastes, smells. The past subjunctive form emphasizes that the comparison is unreal or hypothetical.

Examples

The sky looks as if it were about to snow.Uses visual perception (looks) to compare current sky conditions with snow conditions, emphasizing uncertainty
The music sounds as though it were coming from underwater.Uses auditory perception (sounds) to create an unreal comparison with an impossible situation
The air feels as if summer had already arrived.Uses tactile perception (feels) to compare current temperature with a different season

Common Mistakes to Avoid

❌ Incorrect: It looks as if he is sick

✅ Correct: It looks as if he were sick

Explanation: Use past subjunctive (were) instead of present tense (is) to indicate hypothetical situation

❌ Incorrect: The room smells as though it has been cleaned

✅ Correct: The room smells as though it had been cleaned

Explanation: Use past perfect subjunctive for completed actions in unreal comparisons

Tips for Success

  • Always use past subjunctive forms after as if/as though in these comparisons
  • Consider whether the comparison is about appearance vs. reality
  • Pay attention to the sensory verb that introduces the comparison
  • Use past perfect subjunctive for completed actions in the unreal comparison
