"Partial sun" or "partial shade" descriptions can be confusing and are sometimes used interchangeably. It helps to keep in mind that noontime sun and afternoon sun are intense and hot, but morning sun is relatively cool and gentle. So an hour of afternoon sun is not the same as an hour of morning sun.
Over the years I have found several ways of applying these "partial" descriptions to real life in the garden.
Degree of Sun or Shade
Decide if your spot is overall sunnier or shadier. If the description tells you the plant is really a sun lover but will tolerate part sun, then it is a better candidate for a brighter spot. If the description tells you it is really a shade lover but tolerates partial shade, it is a better candidate for a darker spot.
Soil Moisture
Decide if your soil is usually moist or dry. Moister soil helps plants handle more sun. So if you have a plant that likes full to partial sun, and your soil is dry, it may do better for you in partial sun than in full sun. And typically a plant that likes full to partial shade will need moister soil in a spot with additional sun. So if you have dry soil, put this one in a shadier spot.
Summer Heat
Are your summers exceptionally hot or notably cool? Summer heat can affect the amount of sun a plant can handle. If you live in a climate with extended hot summer weather, most shade to part shade plants will prefer it shadier. In extreme heat, many sun to part sun plants will prefer part sun. Conversely, in a cool summer climate your plants may actually prefer the sunnier end of their range.
