comprendre une ressemblance

You use this phrase like a standard verb-object pair. Most people use it with enfin (finally) to show the realization took time. You can say, Je comprends enfin la ressemblance. It works best when you are discussing people. However, you can also use it for abstract things. You might see a resemblance between two movies. Or perhaps two different styles of architecture. You can also use it in the negative. If you are confused, say Je ne comprends pas la ressemblance. This is a polite way to say you think two people look nothing alike.

This is a great phrase for family reunions. Use it when looking through old dusty photo albums. It is perfect for when a friend introduces you to their sibling. You can use it at an art gallery too. It shows you are paying close attention to the details. It is a very social phrase. It invites others to agree with your observation. Use it in a text when a friend sends a side-by-side photo. It is a warm way to acknowledge shared traits.

Do not use this for things that are identical. If you see two identical pens, do not use it. That is not a 'resemblance'; that is a 'copy.' Avoid using it if the comparison might be insulting. For example, do not say it if someone is compared to a grumpy cartoon character. Unless you are very close friends! Also, do not use it for functional similarities. If two cars both have four wheels, that is not a resemblance. That is just how cars are made. Keep it for physical or stylistic traits.

French culture places a high value on 'l'esprit de famille' (family spirit). At long Sunday lunches, relatives love to debate who has whose nose. They call a striking resemblance le portrait craché (the spitting image). Being able to comprendre une ressemblance shows you are part of the inner circle. It shows you recognize the lineage. It is a way of honoring the family history. The French also love 'physiognomy,' the art of judging character by faces. Seeing a resemblance is like finding a secret link between generations.

You will often hear voir une ressemblance (to see a resemblance). This is the most common version. If you want to sound more sophisticated, try saisir une ressemblance. This means 'to grasp' the resemblance. If the likeness is very strong, you might say frapper (to strike). For example, La ressemblance est frappante. If you are just starting to see it, use entrevoir. This means to catch a glimpse of the similarity. Each variation changes the 'strength' of your realization.
