I'm trying to figure out the main auxiliary/modal verbs in Esperanto for the present, past and future tenses, could you let me know if these are correct? Thanks...
To like - ameti
Present: 'I like' - Mi ametas
Past: 'I liked' - Mi ametis
Future: 'I will like' - Mi ametos
Would like - ametus
Present ('I would like') - Mi ametus
Past: 'I would have liked...' - Mi ????
To want - voli
Present: 'I want' - Mi volas
Past: 'I wanted' - Mi volis
Future: 'I will want' - Mi volos
To need - bezoni
Present: 'I need' - Mi bezonas
Past: 'I needed to...' - Mi bezonis
Future: 'I will need to' - Mi bezonos
To have to/must - devi
Present: 'I have to' - Mi devas
Past: 'I had to' - Mi devis
Future: 'I will have to' - Mi devos
To be able to/can - povi
Present: 'I can' - Mi povas
Past: 'I was able to' / 'I could' - Mi povis
Future: 'I will be able to' - Mi povos
Could (present tense), i.e. 'would be able to' - povus, 'I could' (present) - Mi povus
To have - havi

Future: 'Mi havos'
Was/were - estis
Also, is there a way to say 'should' in Esperanto? 'I should ea't, 'I should sleep', etc? What about the past tense of 'should', i.e. 'should have', 'I should've stayed', etc.
