Pronunciation: [sˈɪkɪʃ] (IPA) 
The spelling of the word "sickish" may seem confusing at first glance. However, it follows the typical English convention of adding the suffix "-ish" to indicate a slight, but not full, quality of a particular state or feeling. In this case, "sick" becomes "sickish," meaning somewhat ill or unwell. The IPA phonetic transcription for "sickish" is /ˈsɪkɪʃ/, with the stress on the first syllable and the "i" pronounced as a short vowel sound.
Sickish is an adjective used to describe a slight or mild feeling of sickness or illness. It refers to a state where one does not feel completely well and may experience symptoms such as nausea, fatigue, or general discomfort, but the symptoms are not severe enough to be classified as a full-fledged illness or disease.
The term sickish suggests a condition that is not debilitating or seriously impairing, but rather a state of being not quite healthy or normal. It can be used to describe various physical or psychological symptoms that may be bothersome or indicative of an underlying issue, but do not reach a level of serious concern.
The word sickish often connotes a sense of unease or discomfort rather than intense pain or suffering. It can be used to describe a range of sensations, from feeling slightly queasy after eating something that doesn't agree with you, to having a mild headache or dizziness. It is important to note that sickish is subjective and may vary from person to person, depending on their tolerance for discomfort or their usual state of health.
Overall, sickish is an adjective that captures a slight feeling of sickness that falls short of being truly ill or unwell. It indicates a condition that is somewhere in between being healthy and being sick, where one may experience mild symptoms but is still able to function and carry out daily activities.
Inclined to be sick; exciting disgust.
