Description:

The term 'slan' refers to health.

Noun:

As a noun, 'slan' means health as a general concept, or the health of a specific being. It can be metaphorically extended to anything that could be considered to have healthy or ungealthy states.

Verb:

As a verb, 'slan' is an  intransitive pali verb which just means to be healthy, or to have a condition of health. So the expression:

We se slan.

can mean 'I am healthy' or 'I am well'. But the expression:

We se zra slan.

is clearly and emphatically positive, asserting good health, and speakers might also say 'fo zra' for more emphasis. You could also say:

We se was slan.

This says that you are not feeling well or in in poor health.

With the modifying term 'rit', it means to heal. For example:

We se rit slan ro na taj.
I am healing from the injury.

The skurun causative of  'slan' also means to heal, but it means to heal someone. Example:

Ja metik teo slan a pocuk.
The doctor healed the child.

Modifier:

The modifier form 'slanys' means 'healthy', again with an inherently positive connotation. The positive connotation can be enhances with 'fo' or 'zrano', and a negative connotation, 'unhealthy', can be conveyed in several ways, 'ikslánys', 'ni slanys', or even 'wasno slanys'.

The derived form 'slanka' derives from the regular pali verb form and means 'healthy one'. The derived form 'slanca', however, references the skurun causative form and is a word for 'healer' or 'remedy'.
