🔹 Denominal Adjectives Ending in -ístico / -ística

Two important morphological points:

First, the RAE prefers analyses such as:

• arte → artístico, rather than artista → artístico, when the meaning is "related to art";
• periodismo → periodístico, rather than periodista → periodístico;
• turismo → turístico, rather than turista → turístico;
• novela → novelístico, rather than novelista → novelístico.

This is because meaning helps determine the morphological base, not merely the most obvious sequence of letters. (RAE §7.7c-d)

Second, there is an important -ismo → -ístico relationship: periodismo → periodístico; atomismo → atomístico; autismo → autístico; ciclismo → ciclístico; dualismo → dualístico; ensayismo → ensayístico; sofismo → sofístico. The RAE discusses these explicitly. (RAE §7.2k)

Important morphophonological details:

• And several perhaps surprising formations are explicitly recognized by the DLE: pianístico, dancístico, tenístico, beisbolístico, and boxístico.
