How do you describe scent?

To me, scent is one of the most important aspects of a garden. But it is difficult to describe. And with everyone it is subject to individual preference, personal history and cultural perspective.
I am anosmic to Freesia, a trait I inherited from my mother. I am told it is a big loss. To me a freesia just smells like a cabbage, like a hybrid tulip.
It is not just flowers that have scent, I daily swipe my hand through my rosemary bush. My “mollis” azaleas have scentless flowers, but at this time of year the leaves have a strong spicey smell even without rubbing – but what spice? But also fruit and roots and stems.
I have read in the past week of someone who doesn’t like Lily of the Valley! and the leaves of English Box (must be USA) were described as repulsive – well in one sense. I, peronally, like Hawthorn flowers, widely disliked.

I usually love the scent of my Scepter'd Isle rose, but every so often it gets a strange medicinal, antiseptic undernote that is slightly nauseating.
I have noticed that a flower's scent is not constant but ages. My Itea Ilicifolia starts with a delicious aroma that is clearly honey, at that stage it attracts bees, As it ages, the honey aroma fades. It doesn't become unpleasant to me but it starts to attract flies.

But something completely new would leave me speechless!!
Even with those shared terms of reference, it’s unlikely that your olfactory experience matches another’s since individual noses detect scent differently, can smell some fragrance notes but not others or the same notes in varying degrees. I have a rose that smells exactly like a citronella candle. Rosemary smells both musky and astringent. Privet is like cat’s pee. But is my perception of citronella or cat’s pee etc. exactly the same as yours? Probably not. Same with colour perception.
Hmmmmm!!
On a similar note I love to hear or read wine or whisky buffs waxing lyrical about a drinks nose or the off the wall descriptions of the flavours lingering and developing on the palate. Intellectualising life’s experiences (especially alcoholism) seems to be a facet of human behaviour. You’re either in the club or you’re not so to speak. As far as being scientific about human perception goes, I wish anybody trying, the best of luck with that.🤔
