Based on the analysis, the feature "loan, has personal loan?" seems to have some relationship with the target variable "Does this client subscribe to a term deposit?". The possible values for the feature are 'no' and 'yes'. 

For clients who do not subscribe to a term deposit (target class "no"), the feature value is consistently 'no'. 

For clients who do subscribe to a term deposit (target class "yes"), the feature values can be both 'no' and 'yes'.

Therefore, the dictionary shows that for the target class "no", the possible values of the feature are only 'no', and for the target class "yes", the possible values of the feature are both 'no' and 'yes'.
